N-Ethyl-o-toluidine (NEOT, N-ethyl-2-methylaniline, CAS 94-68-8) is a secondary aromatic amine combining an o-tolyl ring with a reactive N-ethyl amino group — the ortho isomer of the N-ethyltoluidine family. It is a versatile intermediate for active pharmaceutical ingredients, azo dyes and colour-developer systems, and crop-protection agrochemicals, where the ortho-methyl group provides distinctive steric and electronic tuning. Royalchem Spain supplies it at ≥ 99% purity as a clear to pale-yellow liquid, delivered from our Valladolid distribution hub by drum or IBC.

A secondary-amine building block for active pharmaceutical ingredients and their intermediates, used in cardiovascular and antimicrobial drug synthesis routes and broader medicinal-chemistry programmes.
A coupling and building component for azo dyes, colour-developer systems, and specialty colourants for textiles, leather, and industrial applications; the N-ethyl and ortho-methyl groups help tune shade and fastness.
A building block for pesticide and herbicide active ingredients and their intermediates, contributing to crop-protection chemistry alongside other N-alkyl toluidine isomers.
Standard Packaging:
200 kg HDPE or steel drums, or IBC totes (approx. 1000 kg). Distributed by Royalchem Spain from our Valladolid hub with full documentation package (COA, SDS, REACH, transport documents). 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.
