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 4-(2H-1,3-Benzodioxol-5-yl)-3-methoxy-1-(4-methoxyphenyl)azetidin-2-one.
CATO supplies 4-(2H-1,3-Benzodioxol-5-yl)-3-methoxy-1-(4-methoxyphenyl)azetidin-2-one (CAS 1022252-78-3), a certified reference material (molecular formula C18H17NO5, MW 327.33 g/mol) for analytical method development and quality control.
4-(2H-1,3-Benzodioxol-5-yl)-3-methoxy-1-(4-methoxyphenyl)azetidin-2-one (C18H17NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
