Chemical Structure
Description
1-(3,4-Dihydro-2H-1-Benzopyran-3-yl-4-(4-Fluorophenyl)Piperazine (C19H21FN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-(3,4-Dihydro-2H-1-Benzopyran-3-yl-4-(4-Fluorophenyl)Piperazine (CAS 83823-55-6) is a high-purity analytical reference standard with the molecular formula C19H21FN2O and a molecular weight of 312.38 g/mol.
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.
