Description
2-[3-cyclopropyl-4-(difluoromethyl)-6-(1-ethyl-5-methyl-1h-pyrazol-4-yl)-1h-pyrazolo[3,4-b]pyridin-1-yl]acetic acid (CAS 1006478-14-3), molecular formula C18H19F2N5O2 and molecular weight 375.37 g/mol, is a CATO reference standard with documented purity and traceability.
2-[3-cyclopropyl-4-(difluoromethyl)-6-(1-ethyl-5-methyl-1h-pyrazol-4-yl)-1h-pyrazolo[3,4-b]pyridin-1-yl]acetic acid (C18H19F2N5O2) contains a steroid core, an amide 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.
