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 6-Methoxy-4,5-dihydro-1H-benzo[b]azepin-2(3H)-one.
CATO supplies 6-Methoxy-4,5-dihydro-1H-benzo[b]azepin-2(3H)-one (CAS 72503-43-6), a certified reference material (molecular formula C11H13NO2, MW 191.23 g/mol) for analytical method development and quality control.
6-Methoxy-4,5-dihydro-1H-benzo[b]azepin-2(3H)-one (C11H13NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
