Import 3,5-Diamino Benzoic Acid — Buy in Bulk from Supplier in India

3,5-Diamino Benzoic Acid (CAS 5351-44-2, molecular formula C7H8N2O2) is a difunctional aromatic amine and carboxylic acid used primarily as a diazo and coupling component in azo dye manufacture, as well as a pharmaceutical intermediate for kinase inhibitors and antimicrobial agents. Ajay Organics, based in Ahmedabad, Gujarat, supplies this compound with an emphasis on colour industry applications where the meta-positioned amino groups enable formation of trisazo and polyazo dyes with enhanced substantivity and light fastness. The material typically presents as a grey to brownish crystalline powder, with solubility characteristics dictating its use in aqueous or solvent-based coupling systems.

Commercial production involves nitration of benzoic acid to 3,5-dinitrobenzoic acid followed by catalytic hydrogenation, or reduction via iron-acid or hydrazine hydrate methods. Standard purity targets for dye intermediate grade are 99.0% minimum by HPLC, with critical impurities including mono-amino benzoic acid isomers, unreduced nitro compounds, and inorganic salts from neutralisation. The amino functionality (pKa values approximately 2.5 and 4.2 for the conjugate acids) requires storage under dry, cool conditions to prevent oxidative darkening and carbonate formation. Typical packaging for Indian dye intermediate exports includes 25 kg or 50 kg HDPE drums with inner polyethylene bags, though Ajay Organics' exact offering requires confirmation.

Textile dye manufacturers, pigment producers, and pharmaceutical synthesis operations represent the core buyer segments for this material. In dye chemistry, the compound couples with diazotised para-nitroaniline or H-acid derivatives to produce deep brown, navy, and black shades for cotton and polyester fabrics. Pharmaceutical applications exploit the diamino pattern for heterocycle construction, notably in triazine and pyrimidine ring systems. Importers sourcing from Ajay Organics should clarify the exact grade (dye intermediate vs. pharmaceutical), available batch sizes, and whether the company provides regulatory support files for drug master documentation. The listing does not state MOQ, pricing, or lead time, so these must be negotiated directly with the Ahmedabad facility.

Ajay Organics is located in Ahmedabad, Gujarat 382445, India, a major hub for Indian chemical and dye intermediate manufacturing. The company holds an imported supplier tier and harbour trust tier classification. The response rate is recorded at 0.00% with zero average response hours, which means buyers should initiate contact through multiple channels to confirm current operational capacity and sales team availability. No information is provided on manufacturing plant certifications, R&D capabilities, or specific quality management systems.

The listing does not disclose annual production capacity for 3,5-Diamino Benzoic Acid, number of employees, years in operation, or key domestic and export markets served. There is no mention of GMP compliance, ISO certifications, or environmental clearances from the Gujarat Pollution Control Board. Buyers are advised to request a detailed company profile, manufacturing licence, and evidence of prior export experience to their region before committing to volume orders, particularly for applications requiring pharmaceutical-grade material.
