Chemical Structure
Description
Based on its molecular formula C27H44O2, 17-(1,5-Dimethylhexyl)-3-hydroxy-10,13-dimethyl-2,3,4,5,6,7,9,10,11,12,13,15,16,17-tetradecahydro-1h-cyclopenta[a]phenanthren-15-one contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 400.64 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.
17-(1,5-Dimethylhexyl)-3-hydroxy-10,13-dimethyl-2,3,4,5,6,7,9,10,11,12,13,15,16,17-tetradecahydro-1h-cyclopenta[a]phenanthren-15-one (CAS 50673-97-7), molecular formula C27H44O2 and molecular weight 400.64 g/mol, is a CATO reference standard with documented purity and traceability.
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.
