Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 286.95 g/mol gives methyl 4,5-dibromo-1H-pyrrole-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
methyl 4,5-dibromo-1H-pyrrole-2-carboxylate (CAS 937-16-6), molecular formula C6H9Br2NO2 and molecular weight 286.95 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of methyl 4,5-dibromo-1H-pyrrole-2-carboxylate (C6H9Br2NO2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
