The occurrence of 2-(Methacryloyloxy)ethyl 6-amino-4-(benzo[d][1,3]dioxol-5-yl)-5-cyano-2-methyl-4H-pyran-3-carboxylate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(Methacryloyloxy)ethyl 6-amino-4-(benzo[d][1,3]dioxol-5-yl)-5-cyano-2-methyl-4H-pyran-3-carboxylate (CAS 939893-92-2), a certified reference material (molecular formula C21H20N2O7, MW 412.39 g/mol) for analytical method development and quality control.
The molecular framework of 2-(Methacryloyloxy)ethyl 6-amino-4-(benzo[d][1,3]dioxol-5-yl)-5-cyano-2-methyl-4H-pyran-3-carboxylate (C21H20N2O7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
