Chemical Structure
Description
The occurrence of (3β)-3-(Acetyloxy)-chol-5-ene-24-carboxylic Acid Ethyl Ester is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3β)-3-(Acetyloxy)-chol-5-ene-24-carboxylic Acid Ethyl Ester (CAS 75861-02-8), molecular formula C29H46O4 and molecular weight 458.67 g/mol, is a CATO reference standard with documented purity and traceability.
(3β)-3-(Acetyloxy)-chol-5-ene-24-carboxylic Acid Ethyl Ester (C29H46O4) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
