从India供应商批发进口Acid Red 52 — FOB条款

Acid Red 52 is a synthetic xanthene dye with Colour Index number 45100 and CAS registry 3520-42-1, supplied as a very dark pink powder or crystal by Aryan Dyes & Pigments from their Surat, Gujarat location. The dye exhibits a dye strength of 660 percent with acidic character, an empirical formula of C27H29N2NaO7S2, and a molecular weight of 580.65 g per mol. Its lambda max sits at 554 nm with an extinction coefficient below 85000, confirmed by infrared spectrum analysis.

This acid dye belongs to the rhodamine class of xanthene colorants, valued for their brilliant pink to red shades and strong tinctorial power. The 660 percent strength indicates a highly concentrated preparation, standard for industrial colouration where dosing precision matters. Typical commercial grades range from 80 percent to 400 percent strength; this concentrated form suits bulk manufacturing where dilution or direct high-intensity application is required. The acidic nature means it requires no mordant for protein fibres, bonding directly through ionic attraction to amine groups in wool and nylon.

Primary buyers include textile mills dyeing wool and nylon, cosmetics formulators, leather tanneries, and specialty chemical manufacturers. The dye serves janitorial cleaning products in both strongly alkaline and strongly acidic formulations, leak detection systems, soap production via cold process and melt and pour methods, and leather finishing. B2B purchasers should confirm the specific salt form, particle size distribution for their application method, and any additional certification requirements with the supplier directly.

Aryan Dyes & Pigments operates from Suite 806 at Valentina Business Hub on L.P. Savani Road in New Adajan, Surat, Gujarat 395009, India. The location in Surat places it within one of India's major chemical and textile manufacturing corridors, with proximity to port access at Hazira and Mumbai for export logistics. The supplier holds a harbor trust tier on the platform, though both response rate and average response hours register at zero, indicating no response history is recorded.

The supplier's listing provides detailed product specifications for Acid Red 52 but does not state manufacturing capacity, export experience, certification holdings, or specific client sectors served. No information is given about ISO certification, GMP compliance, or REACH registration status. Buyers should verify the supplier's batch-to-batch consistency protocols, quality control documentation, and whether they offer technical support for dye application optimisation directly.
