Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (E)-1-(1H-Benzo[d][1,2,3]triazol-1-yl)-3-(4-chlorophenyl)prop-2-en-1-one (CAS 519054-04-7), a certified reference material (molecular formula C15H10ClN3O, MW 283.71 g/mol) for analytical method development and quality control.
(E)-1-(1H-Benzo[d][1,2,3]triazol-1-yl)-3-(4-chlorophenyl)prop-2-en-1-one (C15H10ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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).
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.
