Chemical Structure

Abiraterone Impurity 24 CAS 1045-71-2 chemical structure

Description

The occurrence of Abiraterone Impurity 24 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Abiraterone Impurity 24 (CAS 1045-71-2), molecular formula C23H33NO3 and molecular weight 371.51 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Abiraterone Impurity 24 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 371.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
