Chemical Structure
Description
5-Bromo-1-ethyl-4-((4-methoxybenzyl)oxy)-3-methyl-1H-pyrazole (C14H17BrN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
5-Bromo-1-ethyl-4-((4-methoxybenzyl)oxy)-3-methyl-1H-pyrazole (CAS 2633010-08-7) is a high-purity analytical reference standard with the molecular formula C14H17BrN2O2 and a molecular weight of 325.20 g/mol.
