Chemical Structure

1,4-Dibromo-piperazine-2,5-dione CAS 37636-53-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 271.89 g/mol gives 1,4-Dibromo-piperazine-2,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,4-Dibromo-piperazine-2,5-dione (CAS 37636-53-6), a certified reference material (molecular formula C4H4Br2N2O2, MW 271.89 g/mol) for analytical method development and quality control.

1,4-Dibromo-piperazine-2,5-dione (C4H4Br2N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 1,4-Dibromo-piperazine-2,5-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.
