Chemical Structure

(7α,12α)-7,12-Dihydroxy-3-oxo-cholest-4-en-26-oic Acid CAS 136014-52-3 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 (7α,12α)-7,12-Dihydroxy-3-oxo-cholest-4-en-26-oic Acid (CAS 136014-52-3), a certified reference material (molecular formula C27H42O5, MW 446.62 g/mol) for analytical method development and quality control.

(7α,12α)-7,12-Dihydroxy-3-oxo-cholest-4-en-26-oic Acid (C27H42O5) contains a steroid core, 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 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.
