Description

Compared with other compounds in its class, the molecular weight of 179.15 g/mol gives 6-fluoro-2-methyl-4h-benZo[d][1,3]oxazin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 6-fluoro-2-methyl-4h-benZo[d][1,3]oxazin-4-one (CAS 38520-78-4), a certified reference material (molecular formula C9H6FNO2, MW 179.15 g/mol) for analytical method development and quality control.

6-fluoro-2-methyl-4h-benZo[d][1,3]oxazin-4-one (C9H6FNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures 6-fluoro-2-methyl-4h-benZo[d][1,3]oxazin-4-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
