Chemical Structure

Promestriene Impurity 2 CAS CATO-C4X-22052 chemical structure

Description

The occurrence of Promestriene Impurity 2 is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Promestriene Impurity 2 (CAS CATO-C4X-22052) is a certified pharmaceutical impurity reference standard with the molecular formula C23H34O3 and a molecular weight of 358.51 g/mol.

Based on its molecular formula C23H34O3, Promestriene Impurity 2 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 358.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Promestriene Impurity 2 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.
