Chemical Structure
Description
The occurrence of 2-methyl-5-(trifluoromethyl)pyrazol-3-ylboronic acid 344591-91-9 5-Borono-1-methyl-3-(trifluoromethyl)-1H-pyrazole is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-methyl-5-(trifluoromethyl)pyrazol-3-ylboronic acid 344591-91-9 5-Borono-1-methyl-3-(trifluoromethyl)-1H-pyrazole (CAS 344591-91-9), molecular formula C5H10BF3N2O2 and molecular weight 197.95 g/mol, is a CATO reference standard with documented purity and traceability.
2-methyl-5-(trifluoromethyl)pyrazol-3-ylboronic acid 344591-91-9 5-Borono-1-methyl-3-(trifluoromethyl)-1H-pyrazole (C5H10BF3N2O2) 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.
