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.
CATO supplies 7a-Hydroxy-3-oxocholan-24-oic-2,2,4,4-D4 Acid (CAS 99102-72-4), a certified reference material (molecular formula C24H34D4O4, MW 394.58 g/mol) for analytical method development and quality control.
The molecular framework of 7a-Hydroxy-3-oxocholan-24-oic-2,2,4,4-D4 Acid (C24H34D4O4) is characterized by deuterium isotope labeling, a flavonoid 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 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 7a-Hydroxy-3-oxocholan-24-oic-2,2,4,4-D4 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.
