Chemical Structure
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 1-(4-Chlorophenyl)-3-(5-chlorothiophen-2-yl)propenone (CAS 22619-36-9), a certified reference material (molecular formula C8H17Cl2N2O2P, MW 275.11 g/mol) for analytical method development and quality control.
1-(4-Chlorophenyl)-3-(5-chlorothiophen-2-yl)propenone (C8H17Cl2N2O2P) contains an amide group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
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.
