Chemical Structure
Description
The molecular framework of Ethanone, 1-(5,6,7,7a,8,9,10,11-octahydro-4H-benzo[ef]heptalen-2-yl)- (C17H22O) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies Ethanone, 1-(5,6,7,7a,8,9,10,11-octahydro-4H-benzo[ef]heptalen-2-yl)- (CAS 65875-07-2), a certified reference material (molecular formula C17H22O, MW 242.36 g/mol) for analytical method development and quality control.
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.
