4-(((1-(2-Fluoroethyl)-4-methyl-1H-pyrazol-5-yl)amino)methyl)benzene-1,3-diol hydrochloride (CAS 1856091-98-9) is a high-purity analytical reference standard with the molecular formula C13H16FN3O2HCl and a molecular weight of 301.75 g/mol.
4-(((1-(2-Fluoroethyl)-4-methyl-1H-pyrazol-5-yl)amino)methyl)benzene-1,3-diol hydrochloride (C13H16FN3O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
