Ketoprofen Impurity 40 CAS 47087-07-0

Description

Compared with other compounds in its class, the molecular weight of 268.31 g/mol gives Ketoprofen Impurity 40 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ketoprofen Impurity 40 (CAS 47087-07-0) is a certified pharmaceutical impurity reference standard with the molecular formula C17H16O3 and a molecular weight of 268.31 g/mol.

The molecular framework of Ketoprofen Impurity 40 (C17H16O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Ketoprofen Impurity 40 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.
