Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 280.07 g/mol gives 2-(2-Bromo-5-(difluoromethyl)-4-methylpyridin-3-yl)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(2-Bromo-5-(difluoromethyl)-4-methylpyridin-3-yl)acetic acid (CAS 1805436-91-2), a certified reference material (molecular formula C9H8BrF2NO2, MW 280.07 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, 2-(2-Bromo-5-(difluoromethyl)-4-methylpyridin-3-yl)acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.07 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
