Chemical Structure
Description
3-(2-Bromo-4-fluorophenyl)-1-methyl-1h-pyrazol-5-amine (C10H9BrFN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
3-(2-Bromo-4-fluorophenyl)-1-methyl-1h-pyrazol-5-amine (CAS 1152708-98-9), molecular formula C10H9BrFN3 and molecular weight 270.10 g/mol, is a CATO reference standard with documented purity and traceability.
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.
