Atmofair 1-Aminoanthraquinone-5-sulfonic Acid Sodium Salt (CAS 4095-82-3)

1-Aminoanthraquinone-5-sulfonic acid sodium salt (CAS 4095-82-3) has a molecular formula of C14H8NNaO5S and a molecular weight of 325.27 g/mol. It features an amino group (-NH₂), a sulfonate sodium salt group (-SO₃Na), and a quinone moiety attached to the anthracene core. As an anthraquinone derivative, this compound is widely used as a dye intermediate (for synthesizing colorants) and in textile printing processes—its application relies on its chromophoric structure, which enables effective color development. For dye synthesis and industrial use, it must be stored in a sealed container under cool, dry conditions to prevent discoloration or chemical degradation, thereby maintaining its stability and…
