Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 5-Hydroxy 1,7-diphenyl trans-6-hepten 3-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5-Hydroxy 1,7-diphenyl trans-6-hepten 3-one (CAS 87095-74-7), molecular formula C19H20O2 and molecular weight 280.36 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.
