19:0 Cholesterol ester 19:0 Cholesteryl ester 25605-90-7 CE 19:0 CE(19:0) CHEBI:133745 cholest-5-en-3beta-yl nonadecanoate cholesteryl nonadecanoate nonadecanoylcholesterol (CAS 25605-90-7) is a high-purity analytical reference standard with the molecular formula C46H82O2 and a molecular weight of 667.14 g/mol.

Based on its molecular formula C46H82O2, 19:0 Cholesterol ester 19:0 Cholesteryl ester 25605-90-7 CE 19:0 CE(19:0) CHEBI:133745 cholest-5-en-3beta-yl nonadecanoate cholesteryl nonadecanoate nonadecanoylcholesterol contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 667.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
