Chemical Structure
Description
The occurrence of 4-Iodo-1-methyl-1H-pyrazole-3-carboxylic Acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Iodo-1-methyl-1H-pyrazole-3-carboxylic Acid (CAS 6647-98-9) is a high-purity analytical reference standard with the molecular formula C5H5IN2O2 and a molecular weight of 252.01 g/mol.
4-Iodo-1-methyl-1H-pyrazole-3-carboxylic Acid (C5H5IN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
