Chemical Structure
Description
The occurrence of 3-(3-Bromo-2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)piperidine-2,6-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(3-Bromo-2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)piperidine-2,6-dione (CAS 2438125-85-8), molecular formula C9H7BrN2O4 and molecular weight 287.07 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 3-(3-Bromo-2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)piperidine-2,6-dione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 3-(3-Bromo-2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)piperidine-2,6-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
