Chemical Structure

Teprenone Impurity 4 CAS 1117-51-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 262.43 g/mol gives Teprenone Impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Teprenone Impurity 4 (CAS 1117-51-7), a pharmacopoeial impurity reference standard (molecular formula C18H30O, MW 262.43 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C18H30O, Teprenone Impurity 4 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 262.43 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.

As a certified reference material (CRM), Teprenone Impurity 4 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.
