Chemical Structure

Abiraterone Impurity 3 CAS 2484719-14-2 chemical structure

Description

Abiraterone Impurity 3 (CAS 2484719-14-2) is a certified pharmaceutical impurity reference standard with the molecular formula C26H35NO and a molecular weight of 377.56 g/mol.

The molecular framework of Abiraterone Impurity 3 (C26H35NO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
