Direct Black 51 is a synthetic azo dye with the CAS number 34977-63-4 and molecular formula C27H17N5Na2O7S, supplied as a fine powder. It is classified as a direct dye, meaning it bonds directly to cellulose and protein fibers without requiring a mordant. The product is sourced from Gujarat, India, and is formulated for consistent solubility in aqueous dye baths. Its appearance is a deep black powder with low moisture retention, suitable for industrial dyeing processes.
This dye is typically used in leather, paper, and textile applications where high color yield and moderate lightfastness are required. The chemical structure allows for good affinity to collagen in leather and cellulose in paper, making it a common choice for dark shade applications. In textile dyeing, it is often applied under neutral or slightly alkaline conditions. Standard industrial grades contain less than 2% moisture and less than 0.5% insoluble matter, though these values are not guaranteed by the supplier.
Buyers in the leather finishing and paper coloring sectors commonly source this dye for bulk production runs. Packaging is typically in 25kg polyethylene-lined paper bags, though custom packaging may be available on request. The dye is shipped under standard industrial conditions and is not classified as hazardous under GHS. Buyers should confirm compatibility with their specific dyeing equipment and rinse protocols before bulk purchase.
