The chemical is identified by CAS No. 5001-72-9 and carries the EINECS reference 225-669-8. Its molecular composition is C32H21N5Na2O8S2 and it is also known as Direct red 12 B.
As a direct dye, it dissolves readily in organic solvents, a property that makes it suitable for colouring polymer resins. In the dye market, powders of this class are commonly supplied with a purity of 94‑96 percent, a typical range that ensures consistent shade reproduction. Moisture levels are usually limited to below 4 percent to avoid agglomeration during melt processing, which is a standard control point for plastic colourants. The particle size is generally specified between 15 and 70 µm, a typical specification that influences dispersion in the melt and final colour uniformity.
Manufacturers of PVC, polyethylene and polyester products, as well as textile finishing houses, frequently source Direct Red 31 for its vivid red hue. The dye performs well across a pH range of 3 to 9, a typical stability window for direct dyes in both polymer and aqueous systems. The listing does not provide MOQ, payment or shipping details, so prospective buyers should request a formal quotation that clarifies these points. Sparrowings International’s address in Ahmedabad, Gujarat allows importers to verify the supplier’s location before negotiating contracts.

Prospective buyers should first confirm Sparrowings International’s registration with the Gujarat state corporate authority and match the supplied address to official records. Requesting a recent factory audit or third‑party compliance certificate will help verify that the facility meets applicable chemical handling standards. Securing a detailed pro‑forma invoice that lists the exact product specifications will reduce the risk of mismatched shipments.
Because the listing omits specific logistics details, importers need to ask the supplier to confirm lead‑time, preferred Incoterms and shipping ports, with Mundra and Nhava Sheva being common gateways for chemical exports from Gujarat. Typical lead‑times for bulk dye orders range from four to six weeks after order confirmation, and payment terms often involve T/T against a copy of the Bill of Lading or an irrevocable LC, but these should be negotiated directly with the supplier.
Arrange an independent laboratory test on the received batch to verify colour strength, purity and moisture content according to ISO 9001 sampling guidelines. Request a Certificate of Analysis that records the CAS number, purity percentage and any relevant safety data sheet entries. Ensuring the product complies with REACH or local chemical legislation will allow seamless integration into manufacturing without regulatory interruption.
