Atmofair 7-Amino-6H-anthra[9,1-cd]isothiazol-6-one (CAS 6337-02-6)

7-Amino-6H-anthra[9,1-cd]isothiazol-6-one (CAS 6337-02-6) has a molecular formula of C₁₄H₈N₂O S and a molecular weight of 264.30 g/mol. It features an amino group (-NH₂) attached to the fused anthracene-isothiazolone heterocyclic core. As a polycyclic aromatic heterocycle, this compound serves as a key intermediate in the synthesis of functional dyes, pharmaceuticals, and optoelectronic materials—its value stems from its conjugated structure, which endows it with favorable chemical and photophysical properties. For synthetic applications, it must be stored in a sealed container under cool, dark conditions to prevent oxidation or photodegradation, thereby preserving its reactivity.
