Chemical Structure

3-Oxo-7-hydroxychol-4-enoic acid CAS 14772-95-3 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

3-Oxo-7-hydroxychol-4-enoic acid (CAS 14772-95-3) is a high-purity analytical reference standard with the molecular formula C24H36O4 and a molecular weight of 388.54 g/mol.

3-Oxo-7-hydroxychol-4-enoic acid (C24H36O4) contains a flavonoid 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.

CATO manufactures 3-Oxo-7-hydroxychol-4-enoic acid 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.
