Loxoprofen Impurity 165 CAS 63178-03-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Loxoprofen Impurity 165.

As a process- or degradation-related impurity, Loxoprofen Impurity 165 (CAS 63178-03-0, C7H9O3Na) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Loxoprofen Impurity 165 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Loxoprofen Impurity 165 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.
