从India供应商批发进口Acid Blue 1 — FOB条款

Acid Blue 1 from Sparrowings International is a synthetic organic dye with the CAS number 116-95-0, also referred to as Acid Blue V in industry documentation. This powder-form product carries the molecular formula C27H31N2NaO6S2 and is listed under EINECS number 204-165-1, confirming its registration within the European chemical inventory. Originating from Gujarat, India, the dye is classified as an acid dye, which means it binds to substrates such as leather, ink bases, and carbon paper in low pH conditions.

The dye’s structure includes two sulfonate groups, contributing to its solubility in water and its affinity for protein-based materials like leather. Typical for acid dyes in this class, Acid Blue 1 offers strong color fastness to light and washing when applied under standard dyeing conditions. Industry standards for such dyes often specify a minimum purity of 85% for commercial grades, with the remainder comprising moisture and inert salts, though exact purity for this batch should be confirmed with the supplier.

Primarily used in the manufacturing of ink dyestuffs, leather dyestuffs, and paint dyestuffs, Acid Blue 1 is favored by producers of carbon paper and specialty coatings due to its vibrant turquoise-blue hue. Buyers typically source this dye in bulk powder form, with applications spanning textile, paper, and leather industries. For logistics, importers should verify packaging specifications and handling requirements, as acid dyes can be sensitive to moisture and temperature fluctuations during transit.

Sparrowings International operates from D-101, Maruti Homes, in Nana Chiloda, Ahmedabad, Gujarat. The company’s address places it in a commercial zone within Ahmedabad, a hub for chemical and dye manufacturing in western India. As a supplier of Acid Blue 1, Sparrowings International markets the product under its own brand name, indicating direct involvement in production or distribution.

The supplier provides a clear chemical identity for its dye, including CAS and EINECS numbers, which are essential for regulatory compliance in international trade. While the listing does not specify certifications, response metrics, or operational history, the presence of structured chemical data suggests a focus on technical accuracy for industrial buyers. Importers should request additional documentation, such as MSDS and COA, to confirm quality standards.
