Description

Based on its molecular formula C8H16N2O2, 1,3-dimethyl-1h-pyrazole-5-carboxylic acid ethyl ester 2,5-dimethyl-2h-pyrazole-3-carboxylic acid ethyl ester 5744-40-1 Ethyl 1,3-Dimethyl-1H-pyrazole-5-carboxylate ethyl 1,3-dimethylpyrazole-5-carboxylate ethyl 2,5-dimethyl-2h-pyrazole-3-carboxylate ethyl1,3-dimethyl-1h-pyrazole-5-carboxylate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 172.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
