从Pakistan供应商批发进口3 5-Diaminobenzoic Acid — FOB条款

3 5-Diaminobenzoic Acid (CAS 535-87-5) is a tri-substituted benzoic acid bearing amino groups at the 3 and 5 positions and a carboxylic acid at position 1, with molecular formula C7H8N2O2. I & K Enterprises, located at 158-a New Muslim Town in Lahore, Punjab, Pakistan, offers this compound as a chemical intermediate for buyers seeking diaminobenzoic acid derivatives. The source description provides minimal technical detail, so buyers must request comprehensive specification sheets and batch testing data before procurement.

In standard commercial production, 3 5-Diaminobenzoic Acid typically appears as a white to off-white crystalline powder with purity of 98 percent minimum by HPLC or titration, and melting point decomposition beginning near 240 degrees Celsius. The free base form has limited aqueous solubility, with enhanced solubility in alkaline solutions due to carboxylate formation. Industrial synthesis routes include reduction of the corresponding dinitrobenzoic acid or diazotisation/hydrogenation sequences, with potential impurities comprising monoaminated species, unreacted nitro compounds, and inorganic salts from neutralisation steps.

This intermediate finds application in polymer chemistry as a comonomer for high-performance polyamides and polyimides, in pharmaceutical research for heterocyclic scaffold construction, and in dye chemistry for metallised dye systems. I & K Enterprises indicates capacity for both regular and bulk orders, with payment by T/T or bank wire transfer against proforma invoice. No stated MOQ, unit pricing, packaging specifications, or lead times appear in the source data, requiring direct negotiation.
