Product overview
What is 2,5-Dichloroaniline?
2,5-Dichloroaniline (2,5-DCA) is an aromatic amine used mainly as a key intermediate in the manufacture of dyes and organic pigments such as Pigment Yellow 10, as well as pesticides and fine chemicals. Its precise chlorine placement makes it an important coupling component in colourant chemistry.
With the formula C6H5Cl2N (CAS 95-82-9), 2,5-DCA is a crystalline solid produced by hydrogenation of 1,4-dichloro-2-nitrobenzene. The two chlorine atoms enhance its reactivity for nucleophilic substitution and diazotisation, which is central to dye and pigment synthesis.
Because the amino group sits between chlorine atoms at the 2- and 5-positions, the molecule diazotises cleanly and couples predictably — which is why pigment makers specify 2,5-DCA by isomer purity rather than assay alone.
How it is made
2,5-DCA is obtained by catalytic hydrogenation of 1,4-dichloro-2-nitrobenzene — the nitro group is reduced to the amine while both chlorine atoms stay in place.
What that means for your process
- Reactive amino group for diazotisation and coupling
- Chlorine positions fixed at 2 and 5 for shade consistency
- Isomer content controlled to grade, checked by GC
- Low moisture (0.5% max) for stable storage and handling
Applications
What is 2,5-Dichloroaniline used for?
2,5-Dichloroaniline is used primarily as a chemical intermediate. Its main applications, industry by industry, include:
Dyes & pigments
The main use. 2,5-DCA is a workhorse dye & pigment intermediate in azo colourant chemistry.
- Key intermediate for azo dyes and pigments

- Supplied to formulators and synthesis units
Pharmaceuticals & fine chemicals
Specified by custom-synthesis houses where a controlled dichloro-substituted aniline is needed.
- Intermediate for fine chemicals
- Custom synthesis and research scale-up
Process route
How is 2,5-Dichloroaniline used in dye & pigment manufacturing?
2,5-Dichloroaniline is used as a diazo/coupling component in colourant chemistry. Its amino group is diazotised and coupled with other aromatics to form azo dyes and pigments such as Pigment Yellow 10, making 2,5-DCA a core intermediate for the dye and pigment industry.

Safety
Is 2,5-Dichloroaniline hazardous?
Yes. 2,5-Dichloroaniline is a toxic aromatic amine and must be handled with care. It is harmful by inhalation, skin contact and ingestion, and is toxic to aquatic life, so containment is important. With correct PPE, ventilation and storage it is safely handled in industry.
2,5-DCA should be stored in sealed containers in a cool, ventilated place away from heat, light and oxidisers, and handled with gloves, goggles and respiratory protection. Prevent release to drains and waterways. A full MSDS is supplied with every order.
Signal word: Danger
Acute toxic (oral / dermal / inhalation) · toxic to aquatic life
Safe-handling essentials
- Gloves, goggles and respiratory protection at all times
- Work with local exhaust ventilation; avoid dust generation
- Keep containers sealed, cool, dry and out of direct light
- Store away from heat sources and strong oxidisers
- Never allow release to drains, soil or waterways
- Transport as UN 1590 — a regulated dangerous good
