Direct Blue 151 is a synthetic direct dye with the CAS number 6449-35-0 and molecular formula C34H25N5Na2O10S2. It appears as a fine blue powder and is classified under EINECS 229-250-0. This dye is specifically formulated for applications in leather, paper, and textile dyeing, where it delivers consistent coloration without requiring a mordant.
The compound belongs to the anthraquinone class of dyes, typical for direct dyes used in cellulosic fibers. Its solubility in water is moderate, and it exhibits good lightfastness for industrial dyeing processes. Standard particle size ranges between 50 to 150 microns, a typical specification for powdered direct dyes to ensure uniform dispersion during mixing. The dye is free from heavy metal contaminants as per standard industry thresholds for textile-grade chemicals.
Buyers in the leather finishing and specialty paper sectors commonly source this dye for deep blue tones in low-temperature dye baths. It is typically packed in 25kg multi-wall paper bags with inner polyethylene lining. Trade terms are usually FOB Ahmedabad, with minimum order quantities confirmed directly with the supplier. Lead times vary based on batch size and seasonal demand.

Before placing an order, verify the dye’s CAS number, EINECS code, and molecular formula against the supplier’s documentation. Request a Certificate of Analysis (CoA) that includes moisture content, particle size distribution, and foreign matter levels. Confirm that the batch matches the advertised specifications and that no substitute materials are being supplied.
Logistics are typically handled via sea freight from Mundra or Kandla ports, with lead times of 20 to 35 days depending on destination. Incoterms are commonly FOB India, and payment is usually via T/T in advance or LC at sight. Buyers must confirm packaging integrity and labeling compliance with their country’s chemical import regulations.
Conduct a pre-shipment inspection to check for clumping, discoloration, or contamination. Test a sample batch for dye uptake on the intended substrate using standard test methods. Retain a reference sample and request a third-party lab report for heavy metals and azo content if required for your market. Documentation should include safety data sheets and export declarations.
