Chemical Structure

3,6,7,12-Tetrahydroxycholanoic acid CAS 63266-88-6 chemical structure

Description

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.

3,6,7,12-Tetrahydroxycholanoic acid (CAS 63266-88-6), molecular formula C24H40O6 and molecular weight 424.57 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,6,7,12-Tetrahydroxycholanoic acid (C24H40O6) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
