Chemical Structure

Progesterone Impurity 92 CAS CATO-C4X-150292 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 Progesterone Impurity 92.

Progesterone Impurity 92 (CAS CATO-C4X-150292) is a certified pharmaceutical impurity reference standard with the molecular formula C23H34O3 and a molecular weight of 358.51 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, Progesterone Impurity 92 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), Progesterone Impurity 92 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.
