Chemical Structure

Obeticholic Acid Impurity 47 CAS CATO-C4X-115347 chemical structure

Description

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.

Obeticholic Acid Impurity 47 (CAS CATO-C4X-115347) is a certified pharmaceutical impurity reference standard with the molecular formula C26H44O3 and a molecular weight of 404.63 g/mol.

Obeticholic Acid Impurity 47 (C26H44O3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
