3-(Thiophen-2-yl)-3,4-dihydro-2H-benzo[b][1,4]oxazine CAS 1630031-24-1 chemical structure

Description

The occurrence of 3-(Thiophen-2-yl)-3,4-dihydro-2H-benzo[b][1,4]oxazine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(Thiophen-2-yl)-3,4-dihydro-2H-benzo[b][1,4]oxazine (CAS 1630031-24-1), molecular formula C12H11NOS and molecular weight 217.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H11NOS, 3-(Thiophen-2-yl)-3,4-dihydro-2H-benzo[b][1,4]oxazine contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 217.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
