Chemical Structure

WX390 Impurity 7 CAS 32272-48-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including WX390 Impurity 7.

WX390 Impurity 7 (CAS 32272-48-3) is a certified pharmaceutical impurity reference standard with the molecular formula C6H9NS and a molecular weight of 127.21 g/mol.

Owing to a nitrile group, sulfur-containing functionality, WX390 Impurity 7 is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 127.21 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.

CATO manufactures WX390 Impurity 7 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.
