从India供应商批发进口Acid Red 97 | Acid Dyes — FOB条款

Acid Red 97 is an acid dye with the Colour Index designation C.I. Acid Red 22890 and CAS number 10169-02-5, manufactured by Shramik Chemicals at their facility in Ankleshwar, Gujarat. The molecular formula is C32H20N4Na2O8S2, indicating a disodium salt of an azo dye with two sulphonic acid groups that confer water solubility and affinity for protein and polyamide fibres. The supplier offers this material as a red powder with a stated purity of 100%, with free samples available for evaluation before bulk commitment.

The dye follows the typical chemistry of premetallised and monoazo acid dyes, where the sulphonic acid substituents enable application from acidic dyebaths to wool, silk, nylon and leather substrates. Standard commercial grades of Acid Red 97 typically exhibit good levelling properties and moderate to good light fastness on wool, though specific fastness ratings (light, wash, perspiration) should be requested per ISO 105 series test methods. The H.S. code 32041213 classifies this under synthetic organic dyes for textile applications, reflecting its principal end-use in colouration of natural and synthetic polyamide materials.

Textile dyehouses, leather tanneries and paper colouring operations constitute the primary buyer base for this dye grade. Shramik Chemicals lists usage categories spanning leather, paper, textile and wool dyestuffs, suggesting broad formulation compatibility. Buyers should confirm batch-to-batch consistency in shade and strength, typical of acid dye manufacture, and verify whether the supplier provides standardised liquid preparations or only powder form. The Gujarat origin places this within India's dominant chemical manufacturing corridor, with established port access for export shipment.

Shramik Chemicals operates from Plot No. 6904 in the GIDC Industrial Estate at Ankleshwar, Gujarat, a location within one of India's largest chemical manufacturing zones. The supplier holds a harbor trust tier, which represents an entry-level verification status on the trading platform. The response rate shows 0.00% with zero average response hours recorded, indicating no historical response data is available for this profile. Buyers should note that direct communication channels will need to be established and response reliability assessed during initial enquiry.

The company profile does not disclose production capacity, number of employees, revenue figures, specific certifications, or named client references. What the listing does state is product-specific: Acid Red 97 offered under the model number SC/105, with free sample availability and multi-sector usage claims across leather, paper, textile and wool applications. Buyers are advised to request manufacturing quality documentation, including batch analysis certificates and any ISO 9001 or environmental compliance credentials, directly from the supplier during technical qualification.
