Chemical Structure
Description
4,5-Difluoro-1H-pyrrolo[2,3-b]pyridin-2(3H)-one (C7H4F2N2O) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
4,5-Difluoro-1H-pyrrolo[2,3-b]pyridin-2(3H)-one (CAS 1190315-56-0), molecular formula C7H4F2N2O and molecular weight 170.12 g/mol, is a CATO reference standard with documented purity and traceability.
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.
