Description
CATO supplies Ursodeoxycholic Acid Impurity 123 (CAS 10601-78-2), a pharmacopoeial impurity reference standard (molecular formula C24H40O3, MW 376.57 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Ursodeoxycholic Acid Impurity 123 (C24H40O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 376.57 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures Ursodeoxycholic Acid Impurity 123 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
