Isoquinoline Impurity 19 is a critical reference standard used in pharmaceutical quality control to ensure the purity of isoquinoline-based APIs. It serves as a structural analog for method development and validation under ICH Q3A/B guidelines. The compound typically features a specific substitution pattern on the isoquinoline core, with molecular formula C9H7NO and CAS No. 2086-95-5.
Storage requires sealed containers at -20°C under inert atmosphere to prevent degradation. Handling must occur in a fume hood with appropriate PPE due to potential irritant properties. Strict adherence to safety data sheets is mandatory for laboratory personnel.
