Direct Black 38, with CAS number 1937-37-7 and molecular formula C34H25N9Na2O7S2, is a sodium salt azo dye supplied as a fine powder by Sparrowings International. It is designed for use in ink formulations, leather dyeing, plastic coloring, and textile applications, particularly where deep black tones are required without complex processing.
This dye belongs to the class of direct dyes with high affinity for polyamide and cellulosic substrates. Its EINECS number 217-710-3 confirms regulatory listing in EU markets. Typical industrial-grade direct black dyes have moisture content under 4%, and particle sizes under 100 microns for even dispersion. The supplier does not specify dye strength or stability under UV exposure.
End users include manufacturers of inkjet inks, synthetic leather, and colored plastics. Buyers in the packaging and textile industries use this dye for cost-sensitive applications where washfastness is secondary to color depth. Packaging is in sealed polyethylene bags, but MOQ and incoterms are not stated. Buyers must confirm batch-specific test data for consistency and safety compliance.
