Chemical Structure
Description
The occurrence of Methyl 4-bromo-3-(chlorosulfonyl)-1-methyl-1H-pyrazole-5-carboxylate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 4-bromo-3-(chlorosulfonyl)-1-methyl-1H-pyrazole-5-carboxylate (CAS 2061941-00-0) is a high-purity analytical reference standard with the molecular formula C6H6BrClN2O4S and a molecular weight of 317.54 g/mol.
The molecular framework of Methyl 4-bromo-3-(chlorosulfonyl)-1-methyl-1H-pyrazole-5-carboxylate (C6H6BrClN2O4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Methyl 4-bromo-3-(chlorosulfonyl)-1-methyl-1H-pyrazole-5-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
