Description
CATO supplies Ursodeoxycholic Acid Impurity 132 (CAS CATO-C4X-1422132), a pharmacopoeial impurity reference standard (molecular formula C24H40O5, MW 408.57 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C24H40O5, Ursodeoxycholic Acid Impurity 132 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 408.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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), Ursodeoxycholic Acid Impurity 132 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.
