3-(3-Chloro-4-ethoxyphenyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine CAS 1708178-83-9 chemical structure

Description

CATO supplies 3-(3-Chloro-4-ethoxyphenyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine (CAS 1708178-83-9), a certified reference material (molecular formula C16H16ClNO2, MW 289.76 g/mol) for analytical method development and quality control.

3-(3-Chloro-4-ethoxyphenyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine (C16H16ClNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
