Applications
Gasoline Octane Booster, Anti-Knock Additive and Refinery Oil Field Chemicals
N-methylaniline is a multi-function fuel additive. Its primary commercial role is raising the octane number of gasoline, but it also supports anti-knock formulation, corrosion inhibition, fuel stabilization and downstream chemical production.
Anti-Knock Additive
Engine knock is the premature detonation of the air-fuel mixture before the spark event. NMA helps prevent that premature ignition by slowing the radical chain reaction, which makes it useful as an anti-knock additive in high-performance fuel programs. For formulators looking for an octane booster without MMT, NMA provides a non-metallic alternative.
Gasoline Blending Stock Enhancement
When base gasoline components cannot meet the target octane on their own, NMA can close the gap at practical treat rates. Blenders evaluate the response in their actual base fuel, considering RON, MON and fuel sensitivity.
Refinery Oil Field Chemicals
NMA appears in product families used by refineries and oil field chemical suppliers: corrosion inhibition, fuel stabilization and chemical intermediate applications that protect equipment and extend product life.
Fuel Stabilization
Fuels can deteriorate through oxidation, leading to gum formation and shorter storage life. As a stabilizing agent, NMA helps limit oxidation-related changes and supports the quality of stored gasoline and related fuels.
Chemical Intermediate
Beyond fuel use, NMA is a starting material for azo, disperse and reactive dyes, agrochemical intermediates, rubber antioxidants, high-boiling industrial solvents and pharmaceutical synthesis, giving buyers a single molecule with multiple downstream applications.
Performance reference
NMA Treat Rate vs RON Gain
NMA octane response rises with treat rate, while the exact RON gain depends on the base gasoline. The reference curve below shows a representative working range for mid-octane gasoline blending stock and should be validated in your own fuel.
Structure
N-Methylaniline Molecular Structure
The official PubChem 2D structure of N-methylaniline (CID 7515) is used across octane booster and anti-knock applications.
How buyers use NMA in practice
A refinery or blending company may purchase NMA as gasoline blending stock enhancement, dosing it into a gasoline pool to reach the required octane specification. An additive formulator may use NMA inside a finished fuel additive package, combining it with corrosion inhibitors, detergents or stabilizers. A dye, agrochemical or polymer producer may source industrial-grade NMA as a reaction intermediate, and a chemical trader may buy mono methyl aniline in bulk for resale to downstream manufacturers.
Each of these buyers needs the same fundamentals: consistent purity, clear documentation, reliable packaging and a supplier who understands the fuel additive market. That is the role Oulico plays as an n-methylaniline supplier and mma octane booster supplier.
Typical supply expectations
Commercial inquiries should include target quantity, purity, packaging, destination and intended application. Suppliers can then confirm the specification, provide the certificate of analysis, share the safety data sheet and discuss transport options for drums, IBC totes or ISO tanks.
Because regional fuel regulations differ, buyers must verify the additive approval status, maximum treat rate and import requirements for their market. NMA is widely traded, but "widely traded" is not the same as "approved everywhere."
Product
N-Methylaniline: Monomethylaniline, Mono Methyl Aniline, MMA, N-Methylbenzenamine, N-Methylphenylamine
Buyers across the fuel and chemical industries use several names for the same molecule. N-methylaniline (NMA) is also called monomethylaniline, mono methyl aniline, fuel-grade MMA, N-Methylbenzenamine and N-Methylphenylamine. Under every name, the chemistry is the same: an aromatic amine with the formula C7H9N and CAS number 100-61-8, valued as a non-metallic octane booster and anti-knock additive.
Product identity and specification
N-methylaniline is a yellowish liquid with a characteristic amine odor. It is slightly soluble in water and highly soluble in ethanol and most organic solvents, which makes it convenient for blending into gasoline and other fuel systems. As a gasoline octane booster, NMA improves the anti-knock quality of gasoline blending stock and supports higher-octane fuel grades without introducing metallic residue.
As an n-methylaniline supplier and mma octane booster supplier, Oulico supports specification discussions for purity, packaging, documentation and logistics. A certificate of analysis and safety data sheet should accompany every commercial batch, and buyers should confirm the current specification against their intended use.
Why the synonym list matters for buyers
Chemical buyers often search for monomethylaniline, mono methyl aniline, MMA, N-Methylbenzenamine or N-Methylphenylamine even when they mean the same product. Using the correct synonym in customs documents, technical data sheets and internal purchasing systems avoids confusion with unrelated chemicals. Fuel-grade MMA is not methyl methacrylate; in the fuel additive market, MMA refers to N-methylaniline.

Buyer guidance
How to Evaluate NMA for Your Gasoline Blend
This page is built for refineries, fuel blenders, gasoline blending stock buyers, additive formulators and chemical traders evaluating N-methylaniline, monomethylaniline or mono methyl aniline for octane improvement.
Start with your base fuel
Every NMA treat rate conversation should begin with the base gasoline. Confirm the current RON and MON, the target octane specification and the other blending components in the pool. The same NMA addition can produce different octane gains in straight-run, reformate, naphtha or catalytic gasoline.
Use standard octane engine testing for the final decision. Some rapid infrared octane instruments do not detect aromatic amine boosters accurately, so the commercial validation should rely on the correct reference method for your fuel program.
Confirm specification and documents
Before buying N-methylaniline, ask for the certificate of analysis, current safety data sheet and packaging details. Confirm purity, appearance and batch consistency. For export buyers, also check the transport classification and country-specific import documentation.
Check regulatory fit
NMA is widely traded as a non-metallic octane booster and anti-knock additive, but fuel additive approvals differ by market. Verify the maximum treat rate and additive status in your destination country before committing to a commercial blend.
Plan logistics and supply
Oulico supports B2B export inquiries for drums, IBC totes and ISO tanks. When you are ready to buy N-methylaniline or request an NMA octane booster for sale, include target quantity, purity, packaging and destination. A monomethylaniline supplier in Jiangsu, China can then confirm specification, documentation and delivery options.
Direct answers
NMA Buyer Questions, Answered
Answer-first guidance for the questions refineries, blenders and chemical buyers ask before ordering N-methylaniline, monomethylaniline or mono methyl aniline.
How Much Does NMA Increase RON?
Direct answer: in typical mid-octane gasoline blending stock, NMA increases RON by about 2 to 7 points at common treat rates of 0.5% to 3% by volume.
The exact gain depends on the base gasoline, blending components, fuel sensitivity and target specification. Reformate, naphtha, straight-run and catalytically cracked gasoline do not respond identically, so the Performance Reference curve in the Applications section is a planning range rather than a guarantee. Validate RON and MON response with standard octane engine testing in your actual blend before commercial use.
How Should N-Methylaniline Be Stored?
Direct answer: store NMA in tightly sealed original containers in a cool, dry, well-ventilated area, away from heat, ignition sources and incompatible materials.
Keep containers upright and protected from physical damage, inspect them regularly for leaks and follow the temperature, shelf-life and handling guidance on the current safety data sheet. Segregate NMA from strong oxidizers and food or drinking water supplies, and keep spill response materials and appropriate PPE near the storage area.
