Chemical Structure

Estradiol Impurity 32 CAS CATO-C4X-163632 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 408.57 g/mol gives Estradiol Impurity 32 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Estradiol Impurity 32 (CAS CATO-C4X-163632), a pharmacopoeial impurity reference standard (molecular formula C30H32O, MW 408.57 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C30H32O, Estradiol Impurity 32 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 408.57 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.

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 Estradiol Impurity 32 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.
