Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2E)-3-(2H-1,3-Benzodioxol-5-yl)-1-(2,5-dichlorophenyl)prop-2-en-1-one.
(2E)-3-(2H-1,3-Benzodioxol-5-yl)-1-(2,5-dichlorophenyl)prop-2-en-1-one (CAS 565220-10-2) is a high-purity analytical reference standard with the molecular formula C16H10Cl2O3 and a molecular weight of 321.15 g/mol.
(2E)-3-(2H-1,3-Benzodioxol-5-yl)-1-(2,5-dichlorophenyl)prop-2-en-1-one (C16H10Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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).
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.
