Description

4-Chloroaniline ( CAS 106-47-8 ), also known as para-Chloroaniline or p-Chloroaniline, 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 for industrial applications. In dye and pigment production, it serves as a key intermediate for azo dyes used in textile and leather coloring, where consistent purity directly affects color yield and batch reproducibility. Agrochemical formulators use it to produce herbicide and pesticide active ingredients, making raw material specification a critical procurement decision for large scale manufacturing. In polymer and rubber applications, it contributes to the synthesis of curing agents and cross-linkers that influence final material hardness and thermal resistance in various environments. Personal care and cosmetics manufacturers source it as an intermediate in the production of certain hair dye precursors and preservative compounds used in global consumer markets. This chemical is supplied as a white to pale yellow crystalline solid. Technical grade is the standard commercial form, with high-purity grades available for pharmaceutical intermediate use. It is typically packaged in drums or IBCs, with bulk quantities available for industrial-scale procurement. Specialty chemical applications may require specific handling and storage protocols.
