Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 177.17 g/mol gives 3-fluoro-5-methoxypyridine-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-fluoro-5-methoxypyridine-2-carboxylic acid (CAS 1227511-52-5), molecular formula C7H12FNO3 and molecular weight 177.17 g/mol, is a CATO reference standard with documented purity and traceability.
3-fluoro-5-methoxypyridine-2-carboxylic acid (C7H12FNO3) contains an amide group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
