2-(6-(Difluoromethoxy)-7-methoxy-1h-indazol-3-yl)acetic acid (CAS 1306606-55-2), molecular formula C11H10F2N2O4 and molecular weight 272.20 g/mol, is a CATO reference standard with documented purity and traceability.
2-(6-(Difluoromethoxy)-7-methoxy-1h-indazol-3-yl)acetic acid (C11H10F2N2O4) contains a nitrogen-containing heterocyclic scaffold, 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.
