Description

Compared with other compounds in its class, the molecular weight of 176.64 g/mol gives 6-chloro-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-chloro-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine (CAS 1260665-94-8) is a high-purity analytical reference standard with the molecular formula C7H13ClN2O and a molecular weight of 176.64 g/mol.

The molecular framework of 6-chloro-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine (C7H13ClN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
