Atmofair Disperse Yellow 65 (CAS 10116-20-8)

Disperse Yellow 65 (CAS 10116-20-8), a common azo-based disperse dye, typically has a molecular formula consistent with its azo chromophore structure (e.g., C₁₉H₂₀N₄O₄; molecular weight ~354.36 g/mol). It is widely used for dyeing hydrophobic fibers such as polyester, nylon, and acetate. Owing to its conjugated azo group (-N=N-), it imparts bright yellow hues to the dyed substrates. To maintain color stability in textile and industrial dyeing applications, this dye should be stored in a sealed container under cool, dry, and dark conditions—this prevents fading, photodegradation, and moisture absorptions.
