Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 304.42 g/mol gives Abiraterone Impurity 74 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Abiraterone Impurity 74 (CAS 38391-29-6) is a certified pharmaceutical impurity reference standard with the molecular formula C19H28O3 and a molecular weight of 304.42 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, Abiraterone Impurity 74 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Abiraterone Impurity 74 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.
