Direct Black 38（Cat No.:M122289）is a synthetic azo dye commonly used for coloring textiles, leather, and paper due to its high solubility in water and strong affinity for cellulose fibers. Chemically classified as a diazo compound, it produces a deep black shade with excellent coverage. Beyond industrial use, it has been studied for its toxicological and environmental impact, as azo dyes can undergo reductive cleavage to form aromatic amines, raising safety and ecological concerns. Direct Black 38 also serves as a model compound in biodegradation and wastewater treatment research.
