Chemical Structure

Progesterone Impurity 93 CAS CATO-C4X-150293 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 416.55 g/mol gives Progesterone Impurity 93 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Progesterone Impurity 93 (CAS CATO-C4X-150293) is a certified pharmaceutical impurity reference standard with the molecular formula C25H36O5 and a molecular weight of 416.55 g/mol.

The molecular framework of Progesterone Impurity 93 (C25H36O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Progesterone Impurity 93 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.
