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.
1-{6-[4-(4-fluorophenyl)piperazin-1-yl]-2-methylpyridin-3-yl}ethan-1-one (CAS 478260-06-9) is a high-purity analytical reference standard with the molecular formula C18H20FN3O and a molecular weight of 313.37 g/mol.
1-{6-[4-(4-fluorophenyl)piperazin-1-yl]-2-methylpyridin-3-yl}ethan-1-one (C18H20FN3O) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
