The occurrence of Abiraterone Impurity 83 is closely related to a steroid core, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Abiraterone Impurity 83 (CAS 3100035-71-7), a pharmacopoeial impurity reference standard (molecular formula C19H25IO, MW 396.31 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Abiraterone Impurity 83 (C19H25IO) is characterized by a steroid core, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 83 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.
