2,4-dichloroaniline

2,4-Dichloroaniline (CAS 554-00-7), commonly referred to as 2,4-DCA, is an aromatic amine intermediate used across dye, agrochemical, and polymer manufacturing. It functions primarily as a building block for synthesizing pigments, biocides, and curing agents rather than as a finished product in its own right. In textile and leather processing, it serves as a precursor.

This chemical is essential for azo dyes and pigments that provide colorfast performance on fiber and hide substrates. Polymer formulators use it as a curing agent and cross-linker for polyurethane and epoxy systems. Controlled chain extension is critical to final mechanical properties in these industrial applications. In agrochemical production, it is an established intermediate in the synthesis of herbicides and fungicides.

This makes it a primary procurement target for active ingredient manufacturers globally. Personal care and cosmetic manufacturers source it for the production of hair dye intermediates for consistent chemistry. Its reactivity profile enables reliable oxidative coupling chemistry in various formulations. The material is supplied as a solid at ambient temperature, typically in flake or crystalline form for easy handling.

Technical grade is the standard commercial specification, with purity levels commonly at 99% or higher. Packaging options generally include fiber drums and intermediate bulk containers suited to industrial volumes.
