4-Chloro-2-(trifluoromethyl)aniline

4-Chloro-2-(trifluoromethyl)aniline (CAS 445-03-4) is a fluorinated aromatic amine supplied under trade designations including C.I. 37055, Fast Scarlet Salt VD, and Scarlet Salt Nvd. It carries no assigned E-code. The compound belongs to the halogenated amine class and is catalogued under HS code 29214300.

In textile and leather processing, it functions as a diazonium-forming intermediate, coupling with naphthol substrates on fiber to produce azo colorants with strong fastness properties. In antimicrobial formulations, the electron-withdrawing trifluoromethyl and chloro substituents enhance membrane-disrupting activity, making it applicable in preservation systems for personal care and pharmaceutical manufacturing.

This material is available as a clear yellow liquid suitable for direct use in synthesis or formulation workflows. Suppliers operating under REACH registration provide safety data documentation aligned with EU GHS requirements. Packaging is typically offered in drum quantities for industrial procurement.
