Ursodeoxycholic Acid impurity 90 CAS CATO-C4X-142290

Description

Compared with other compounds in its class, the molecular weight of 434.65 g/mol gives Ursodeoxycholic Acid impurity 90 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ursodeoxycholic Acid impurity 90 (CAS CATO-C4X-142290), a pharmacopoeial impurity reference standard (molecular formula C27H46O4, MW 434.65 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Ursodeoxycholic Acid impurity 90 (C27H46O4) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures Ursodeoxycholic Acid impurity 90 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.
