Chemical Structure

Ethyl 6-chloro-4-((3-(trifluoromethyl)phenyl)sulfonyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine-2-carboxylate CAS 866134-62-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 449.83 g/mol gives Ethyl 6-chloro-4-((3-(trifluoromethyl)phenyl)sulfonyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl 6-chloro-4-((3-(trifluoromethyl)phenyl)sulfonyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine-2-carboxylate (CAS 866134-62-5), a certified reference material (molecular formula C18H15ClF3NO5S, MW 449.83 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 6-chloro-4-((3-(trifluoromethyl)phenyl)sulfonyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine-2-carboxylate (C18H15ClF3NO5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
