Aniline-2,5-Disulfonic Acid Supplier & Distributor in India

ChemicalBull is a reliable Aniline-2,5-Disulfonic Acid supplier, distributor, wholesaler and exporter in India, supporting dye manufacturers, pigment producers, pharmaceutical intermediate companies and specialty chemical businesses. We offer bulk and recurring supply with suitable packing, batch documents and organised delivery support.

Aniline-2,5-Disulfonic Acid is an aromatic sulfonic acid intermediate mainly used in the manufacture of dyes, pigments and selected specialty chemical intermediates. Its molecular structure contains one amino group and two sulfonic acid groups, making it suitable for further chemical reactions and colour-chemical production.

ChemicalBull supports B2B buyers looking for Aniline-2,5-Disulfonic Acid bulk price, purity specifications, COA, MSDS, TDS, packing and regular supply. Buyers can share their required purity, quantity, application and delivery location for commercial supply details.

Overview of Aniline-2,5-Disulfonic Acid

Aniline-2,5-Disulfonic Acid is also known as 2,5-Disulfoaniline and 2-Amino-1,4-Benzenedisulfonic Acid. 

The product is generally available as an off-white to light-coloured powder or crystalline solid. It contains two strongly acidic sulfonic acid groups, which make it useful in reactions used to prepare water-compatible dye and chemical intermediates.

Aniline-2,5-Disulfonic Acid may also be supplied commercially in salt form, including monosodium salt. The free acid and monosodium salt have different CAS numbers, so buyers should confirm the exact form required before ordering. The monosodium salt is commonly identified separately as CAS 98-44-2.

Applications of Aniline-2,5-Disulfonic Acid

Dye Intermediate Manufacturing

Aniline-2,5-Disulfonic Acid is mainly used as an intermediate in the manufacture of selected dyes.

Its amino group can take part in diazotisation and coupling chemistry, while the sulfonic acid groups can support water compatibility in the resulting dye structures. This makes the product useful in colour-chemical manufacturing.

Acid Dye Production

The product is used as an intermediate in selected acid dye manufacturing processes. Acid dyes are widely used in textile colouring where suitable water solubility and strong colour performance are required.

Aniline-2,5-Disulfonic Acid acts as a building block rather than as a finished dye.

Reactive Dye Intermediates

The sodium salt and related forms of Aniline-2,5-Disulfonic Acid are also associated with reactive dye synthesis. These intermediates help manufacturers build more complex dye structures used in textile processing.

Final colour and dye performance depend on the complete chemical structure and manufacturing process.

Organic Pigment Intermediates

Aniline-2,5-Disulfonic Acid can be used in selected pigment-intermediate production where an amino-substituted aromatic disulfonic acid structure is required.

Pigment manufacturers should define purity and impurity requirements according to the downstream colour chemistry.

Pharmaceutical Intermediate Applications

The compound may also be used as a pharmaceutical intermediate in selected synthesis processes. Its use depends on the required downstream molecule and process specification.

The required grade should be selected according to the buyer’s internal quality requirements.

Specialty Chemical Synthesis

Aniline-2,5-Disulfonic Acid can serve as a building block in specialised organic synthesis. Its amino and sulfonic acid groups provide useful reactive positions for further chemical conversion.

It may therefore be used in selected fine chemical and functional intermediate production.
