Chemical Structure

Taurochenodeoxycholic Acid CAS 516-35-8 chemical structure

Description

Taurochenodeoxycholic Acid (C26H45NO6S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).

Taurochenodeoxycholic Acid (CAS 516-35-8) is a high-purity analytical reference standard with the molecular formula C26H45NO6S and a molecular weight of 499.70 g/mol.

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.

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.
