Chemical Structure
Description
The occurrence of methyl 4-bromo-5-methyl-1H-pyrrole-2-carboxylate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
methyl 4-bromo-5-methyl-1H-pyrrole-2-carboxylate (CAS 203207-18-5), molecular formula C7H12BrNO2 and molecular weight 222.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of methyl 4-bromo-5-methyl-1H-pyrrole-2-carboxylate (C7H12BrNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
