Chemical Structure
Description
The molecular framework of 4-bromo-3-(bromomethyl)-1-methyl-1H-pyrazole (C5H10Br2N2) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
4-bromo-3-(bromomethyl)-1-methyl-1H-pyrazole (CAS 1383575-45-8) is a high-purity analytical reference standard with the molecular formula C5H10Br2N2 and a molecular weight of 257.95 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
