What is 2-chloroaniline?
2-Chloroaniline (CAS 95-51-2), also known as o-Chloroaniline, is an aromatic amine intermediate. Also marketed as o-Chloroaniline.
Where is 2-chloroaniline used?
- Dye manufacturing: building block for azo dyes and pigments
- Textile and printing: precursor in azo dye synthesis for colorants on fabric, paper and packaging
- Pharmaceutical production: synthesis of active intermediates, with ortho-chloro substitution directing reaction pathways during API construction
- Polymer and rubber processing: curing agent and cross-linker for elastomeric and plastic components
- Agrochemical synthesis: starting material for herbicides and pesticides, where chlorinated aniline derivatives define biological activity
- It is a liquid at ambient conditions.
Commercial specifications
- Technical grade for industrial synthesis; higher-purity specifications offered
- Packaging: drums to IBC containers, for laboratory-scale procurement and bulk industrial supply
