从India供应商批发进口Acid Red 131 — FOB条款

Acid Red 131 is a synthetic acid dye with the CAS number 12234-99-0, supplied by Sparrowings International as a powder-form dyestuff for leather, plastics, and textiles. The molecular formula is C30H21N3NaO9S2, and it is registered under EINECS No. 602-541-3. Originating from Gujarat, India, this dye is classified under the Acid Brilliant Red 3BN alias and is specifically formulated for polyamide applications in addition to broader textile and leather uses.

The dye’s structure includes sodium sulfonate groups, which enhance water solubility and affinity for protein and polyamide fibres. Typical for acid dyes, it exhibits strong colour fastness under standard dyeing conditions, with a pH range of 2 to 4 for optimal uptake. Industry-standard purity for such dyes is often above 85%, with moisture content typically below 5% to prevent clumping during storage and application.

Buyers of Acid Red 131 include textile manufacturers seeking vibrant red shades for wool, silk, and nylon, as well as leather finishers and plastic producers requiring consistent colour dispersion. Sourcing from Gujarat offers proximity to major ports like Mundra and Nhava Sheva, reducing transit times. Importers should confirm solubility, pH stability, and compatibility with their substrate before bulk orders, as these factors directly impact dyeing efficiency and final product quality.

Sparrowings International operates from D-101, Maruti Homes, in Nana Chiloda, Ahmedabad, Gujarat. The supplier is classified under the harbor trust tier, indicating a baseline level of verified business presence. Their listed address places them within a commercial hub of Gujarat, a region known for its chemical and dye manufacturing clusters.
