Chemical Structure
Description
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.
2,4-Diphenyl-5,6-dihydrobenzo[h]chromen-1-ium bromide (CAS 76192-30-8), molecular formula C25H19OBr and molecular weight 415.33 g/mol, is a CATO reference standard with documented purity and traceability.
2,4-Diphenyl-5,6-dihydrobenzo[h]chromen-1-ium bromide (C25H19OBr) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
