Acid Red 186 is a synthetic acid dye with CAS number 52677-44-8, also known in industry as Complex Pink B. Supplied by Sparrowings International from Gujarat, India, this powder-form dye has the molecular formula C20H14N4Na2O8S2 and EINECS number 258-095-1. It is classified as an acid dye primarily used for colouring leather, textiles and polyamide fibres, delivering consistent, vibrant hues in industrial applications.
The dye’s chemical structure supports strong affinity for protein and polyamide substrates, ensuring uniform penetration and colourfastness. Acid Red 186 typically exhibits good solubility in water, which facilitates even application in dye baths. Standard for acid dyes in this class, it is often used in slightly acidic to neutral pH conditions (pH 4-7 typical) to achieve optimal fixation. The powder form allows for easy handling and precise dosing in bulk production environments.
Manufacturers of leather goods, textiles and synthetic fibres source Acid Red 186 for its reliability in producing deep red shades with resistance to washing and light exposure. Buyers in India and international markets often procure this dye in bulk, with typical packaging in 25 kg or 50 kg bags. Sourcing from Sparrowings International in Gujarat offers proximity to major textile hubs, reducing transit times for domestic and export orders.

Before ordering Acid Red 186 from Sparrowings International, verify the dye’s compliance with your target market’s chemical regulations, such as REACH in the EU or EPA standards in the US. Request a certificate of analysis to confirm the CAS number, molecular formula and purity levels, as these directly impact colour consistency and performance in your production process.
Confirm logistics details such as lead time, which can vary based on Sparrowings International’s production schedule and your order volume. Clarify Incoterms, with FOB Ahmedabad or CIF to your port being common options for Indian dye exports. Discuss payment terms, as suppliers often require a percentage upfront for first-time buyers, with the balance due upon shipment or delivery.
For quality checks, insist on a pre-shipment inspection to verify the dye’s appearance, solubility and colourfastness. Request a sample for lab testing to assess its performance on your specific substrates. Ensure all documentation, including the material safety data sheet and compliance certificates, accompanies the shipment to avoid customs delays or rejections at your destination.
