Chemical Structure

Lornoxicam Impurity 25 CAS CATO-C4X-201625 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 268.74 g/mol gives Lornoxicam Impurity 25 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Lornoxicam Impurity 25 (CAS CATO-C4X-201625) is a certified pharmaceutical impurity reference standard with the molecular formula C7H9ClN2O3S2 and a molecular weight of 268.74 g/mol.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Lornoxicam Impurity 25 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures Lornoxicam Impurity 25 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
