N-Ethyl-m-toluidine (MEMT, N-ethyl-3-methylaniline, CAS 102-27-2) is a secondary aromatic amine and a versatile intermediate, combining an m-tolyl ring with a reactive N-ethyl amino group. Its principal use is as a building block for dyes and pigments — azo, triarylmethane, and related colourants — with further uses across the rubber, photographic, and fine-chemical industries. Royalchem Spain supplies it at ≥ 99% purity as a light-yellow oily liquid, delivered from our Valladolid distribution hub by drum or IBC.

A coupling and building component for azo, triarylmethane, and cyanine dyes used in textiles, leather, and printing inks; the N-ethyl and meta-methyl groups help tune shade, brightness, and substantivity.
An intermediate for rubber antioxidants, accelerators, and stabilisers, and for photographic developers, sensitisers, and stabilisers used in colour films and photographic papers.
A secondary-amine building block for catalysts, ligands, biological stains and indicators, and modern synthetic reagents, and a candidate precursor in pharmaceutical research.
Standard Packaging:
200 kg HDPE or steel drums, or IBC totes (approx. 1000 kg). Distributed by Royalchem Spain from our Valladolid hub. Shelf life 24 months in original sealed packaging.
Storage Conditions:
Store in tightly sealed containers in a cool, dry, dark, well-ventilated area, away from heat, ignition sources, oxidising agents, and acids; nitrogen blanketing is recommended, as this aromatic amine darkens on exposure to air and light. Toxic — handle with respiratory protection and full PPE.
