Chemical Structure
Description
3-bromo-1-[2-(difluoromethoxy)phenyl]pyrrolidin-2-one (CAS 1311318-38-3), molecular formula C11H10BrF2NO2 and molecular weight 306.10 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-bromo-1-[2-(difluoromethoxy)phenyl]pyrrolidin-2-one (C11H10BrF2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 306.10 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures 3-bromo-1-[2-(difluoromethoxy)phenyl]pyrrolidin-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
