Chemical Structure

Hydrocortisone Impurity 55 CAS CATO-C4X-140155 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 Hydrocortisone Impurity 55.

CATO supplies Hydrocortisone Impurity 55 (CAS CATO-C4X-140155), a pharmacopoeial impurity reference standard (molecular formula C21H32O5, MW 364.48 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C21H32O5, Hydrocortisone Impurity 55 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 364.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Hydrocortisone Impurity 55 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.
