2, 5 Dichloro Aniline [2,5DCA]

2,5-Dichloroaniline (2,5DCA) is an aromatic amine compound with the molecular formula C₆H₅Cl₂N and CAS No. 95-82-9. It appears as a white to light yellow crystalline solid and is slightly soluble in water but readily soluble in organic solvents. 2,5DCA is a key intermediate in the synthesis of azo dyes, pigments (notably Pigment Yellow 10), and agrochemicals. Its dichlorinated structure enhances stability and reactivity, making it ideal for coupling reactions and diazotization processes. It is commonly used in the production of colorants for textiles, plastics, and coatings, offering excellent lightfastness and thermal resistance. Manufactured under controlled conditions, 2,5DCA complies with global standards including REACH and ISO, and is available in technical and high-purity grades. In India, it is produced by hydrogenation of 1,4-dichloro-2-nitrobenzene and is widely supplied to dye, pigment, and pharmaceutical industries. Its versatility and cost-efficiency make it a preferred choice for formulators seeking reliable aromatic intermediates.
