Obeticholic Acid Impurity 27 CAS 863239-59-2

Description

Compared with other compounds in its class, the molecular weight of 430.62 g/mol gives Obeticholic Acid Impurity 27 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Obeticholic Acid Impurity 27 (CAS 863239-59-2), a pharmacopoeial impurity reference standard (molecular formula C27H42O4, MW 430.62 g/mol) used for the identification and quantification of trace impurities in APIs.

Obeticholic Acid Impurity 27 (C27H42O4) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
