6-Chloro-3-(3-chloro-4-ethoxyphenyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine CAS 1710472-06-2

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

6-Chloro-3-(3-chloro-4-ethoxyphenyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine (CAS 1710472-06-2) is a high-purity analytical reference standard with the molecular formula C16H15Cl2NO2 and a molecular weight of 324.20 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloro-3-(3-chloro-4-ethoxyphenyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
