Acid Black 24 is an acid dye with the chemical formula C36H23N5Na2O6S2 and CAS number 3071-73-6, supplied in powder form by Sparrowings International from Gujarat. This product, also known as Acid Fast Black 2A, is classified under EINECS number 221-343-4 and is primarily used as a dyestuff for leather, textiles, and polyamide materials. Its molecular structure and sodium salt composition make it suitable for applications requiring stable, deep black shades on protein and synthetic fibres.
The dye is a standard acid-class product, typical for industrial textile and leather finishing where colourfastness and uniformity are critical. Acid dyes like this one are known for their solubility in water and ability to bond ionically with amino groups in fibres, producing vibrant, long-lasting colours. Typical industry use includes dyeing wool, silk, and nylon, where its resistance to bleeding and fading under standard washing conditions is a key advantage.
Buyers of Acid Black 24 often source it for bulk production in garment manufacturing, leather goods, and polyamide-based textiles. The dye is commonly used in processes where precise colour matching and consistency across large batches are required. Sourcing from Gujarat offers access to a hub of chemical manufacturing, with Sparrowings International providing local supply chain benefits for importers targeting South Asian markets.
