methyl 7-fluoro-3-methyl-2-oxo-1,3-benzoxazole-4-carboxylate CAS 2387595-69-7

Description

As a certified reference material (CRM), methyl 7-fluoro-3-methyl-2-oxo-1,3-benzoxazole-4-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

methyl 7-fluoro-3-methyl-2-oxo-1,3-benzoxazole-4-carboxylate (CAS 2387595-69-7), molecular formula C10H14FNO4 and molecular weight 231.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, methyl 7-fluoro-3-methyl-2-oxo-1,3-benzoxazole-4-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
