Chemical Structure

methyl 7-fluoro-1,2-benzoxazole-3-carboxylate CAS 2060053-38-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 195.15 g/mol gives methyl 7-fluoro-1,2-benzoxazole-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies methyl 7-fluoro-1,2-benzoxazole-3-carboxylate (CAS 2060053-38-3), a certified reference material (molecular formula C9H6FNO3, MW 195.15 g/mol) for analytical method development and quality control.

methyl 7-fluoro-1,2-benzoxazole-3-carboxylate (C9H6FNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
