Import Basic Brown 1 — Buy in wholesale FOB from Supplier in India

Basic Brown 1 (C.I. Basic Brown 1, CAS 10114-58-6) is an azo-based cationic dye supplied by Sparrowings International from Ahmedabad, Gujarat, with the molecular formula C18H20Cl2N8 and EINECS registration 233-314-3. The product is also known commercially as Basic Brown G, indicating a standardised shade position within the basic brown dye range. Sparrowings International offers this as a powder-form product for leather, paper and textile coloration applications. The Ahmedabad location provides access to Gujarat's chemical manufacturing infrastructure and export logistics through Mundra and Kandla ports.

The dye structure combines an azo chromophore with cationic ammonium groups, producing affinity for anionic substrates including vegetable-tanned leather, acidic paper stocks and acrylic fibres. Standard commercial grades of Basic Brown 1 typically exhibit dye content between 75-85 percent, with the balance comprising standardising salts and moisture. The dihydrochloride salt form indicated by the molecular formula confers water solubility under acidic to neutral pH conditions. Typical application methods for leather include drum dyeing at controlled temperature and pH, while textile applications often involve exhaust dyeing of acrylics or modified polyesters with acetic acid pH adjustment. The brown shade position fills a gap between yellowish-brown and reddish-brown basic dye options, offering moderate light fastness on substrates where basic dyes are technically appropriate.

Target buyers include leather tanneries requiring consistent penetration and levelness on full-grain and corrected-grain hides, paper mills colouring speciality grades and security papers, and textile producers dyeing acrylic knitwear and carpets. The powder form suits bulk handling and automated weighing systems. Importers should confirm with Sparrowings International the specific application sector for which their grade is optimised, as leather and textile grades may differ in salt content, pH stability and auxiliary compatibility. Standard packaging, minimum order quantities and lead times are not specified in the source data and require direct supplier confirmation.
