Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 273.56 g/mol gives 3-(3-Bromophenyl)-5-methyl-1H-pyrazole hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(3-Bromophenyl)-5-methyl-1H-pyrazole hydrochloride (CAS 324054-75-3) is a high-purity analytical reference standard with the molecular formula C10H9BrN2HCl and a molecular weight of 273.56 g/mol.
3-(3-Bromophenyl)-5-methyl-1H-pyrazole hydrochloride (C10H9BrN2HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/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.
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.
CATO manufactures 3-(3-Bromophenyl)-5-methyl-1H-pyrazole hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
