5-(2,4-Dimethoxyphenyl)-1H-pyrazol-3-amine hydrochloride (CAS 1025447-47-5), molecular formula C11H13N3O2HCl and molecular weight 255.70 g/mol, is a CATO reference standard with documented purity and traceability.
5-(2,4-Dimethoxyphenyl)-1H-pyrazol-3-amine hydrochloride (C11H13N3O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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.
