Chemical Structure
Description
4-(5-Chlorothiophen-2-yl)azetidin-2-one (C7H6ClNOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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).
CATO supplies 4-(5-Chlorothiophen-2-yl)azetidin-2-one (CAS 777884-07-8), a certified reference material (molecular formula C7H6ClNOS, MW 187.65 g/mol) for analytical method development and quality control.
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.
