Chemical Structure
Description
3,4-Dibromo-1-(pyridin-3-yl)-1H-pyrrol-2(5H)-one (CAS 1706461-36-0) is a high-purity analytical reference standard with the molecular formula C9H6Br2N2O and a molecular weight of 317.96 g/mol.
The molecular framework of 3,4-Dibromo-1-(pyridin-3-yl)-1H-pyrrol-2(5H)-one (C9H6Br2N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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.
