Abiraterone Impurity 22 CAS 114611-53-9

Description

The occurrence of Abiraterone Impurity 22 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 22 (CAS 114611-53-9), a pharmacopoeial impurity reference standard (molecular formula C21H29IO2, MW 440.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, a hydroxyl group, an ether linkage, iodine substitution, Abiraterone Impurity 22 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 440.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
