Chemical Structure

3β-Cholic Acid CAS 3338-16-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 3β-Cholic Acid (CAS 3338-16-7), a certified reference material (molecular formula C24H40O5, MW 408.57 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, 3β-Cholic Acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
