Chemical Structure
Description
The occurrence of Abiraterone Acetate 7-Keto Impurity 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.
CATO supplies Abiraterone Acetate 7-Keto Impurity (CAS CATO-C4X-107072), a pharmacopoeial impurity reference standard (molecular formula C26H31NO3, MW 405.53 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C26H31NO3, Abiraterone Acetate 7-Keto Impurity contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 405.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), Abiraterone Acetate 7-Keto Impurity meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
