Import Auramine O — Buy in Bulk from Supplier in India

Auramine O, also catalogued as Basic Yellow 2 with the Colour Index number 41000 and CAS registry 2465-27-2, is a diarylmethane cationic dye supplied by Aryan Dyes & Pigments from their base in Surat, Gujarat. The product presents as yellow needle crystals in its pure form and exhibits very high solubility in water alongside solubility in ethanol. This listing targets B2B buyers seeking bulk quantities of this basic dye for textile and non-textile coloration applications across acrylic, silk, cotton, leather, paper, and viscose substrates.

The dye belongs to the diarylmethane class, a structural category characterised by a central carbon linked to two aromatic rings, which confers the strong cationic charge and fluorescence properties that distinguish Auramine O from other basic yellow alternatives. In typical industrial practice, the product is supplied as a powder or concentrated aqueous preparation, with standard purity grades for textile applications generally exceeding 90 percent dye content. The material is compatible with tannin mordant systems and performs in direct printing and blotch discharge printing workflows on mordanted cotton. Buyers should confirm the exact dye content, salt content (typically sodium chloride or sodium sulphate as diluent), and moisture specification with the supplier prior to formulation.

Primary end-use sectors include textile mills processing acrylic and natural fibres, leather tanneries, paper manufacturers, and specialty ink formulators. The product also serves laboratory and clinical markets where its fluorescent properties are exploited for acid-fast bacterial staining, notably in tuberculosis diagnostics. Aryan Dyes & Pigments lists this material from their Surat location, a major Indian hub for dye and pigment manufacturing. Trade terms, MOQ, lead times, and packaging formats are not specified in the available data and must be confirmed directly with the supplier.
