3-Bromo-1-(4-bromo-3-methylphenyl)pyrrolidin-2-one (CAS 1343739-99-0), molecular formula C11H11Br2NO and molecular weight 333.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Bromo-1-(4-bromo-3-methylphenyl)pyrrolidin-2-one (C11H11Br2NO) 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 its high hydrophobicity (logP), 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.
