Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 262.08 g/mol gives methyl 2-amino-5-bromo-3-fluoro-6-methylbenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
methyl 2-amino-5-bromo-3-fluoro-6-methylbenzoate (CAS 1862776-46-2) is a high-purity analytical reference standard with the molecular formula C9H9BrFNO2 and a molecular weight of 262.08 g/mol.
methyl 2-amino-5-bromo-3-fluoro-6-methylbenzoate (C9H9BrFNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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. 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.
As a certified reference material (CRM), methyl 2-amino-5-bromo-3-fluoro-6-methylbenzoate 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.
