Salicylic Acid Impurity 23 CAS CATO-C4X-190223

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Salicylic Acid Impurity 23.

Salicylic Acid Impurity 23 (CAS CATO-C4X-190223) is a certified pharmaceutical impurity reference standard with the molecular formula C10H12O6S and a molecular weight of 260.26 g/mol.

Based on its molecular formula C10H12O6S, Salicylic Acid Impurity 23 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 260.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Salicylic Acid Impurity 23 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
