Chemical Structure
Description
CATO supplies 2,3-Dichloro-5H-pyrrolo[3,4-b]pyrazine-5,7(6H)-dione (CAS 213549-73-6), a certified reference material (molecular formula C6HCl2N3O2, MW 218.00 g/mol) for analytical method development and quality control.
2,3-Dichloro-5H-pyrrolo[3,4-b]pyrazine-5,7(6H)-dione (C6HCl2N3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. 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), 2,3-Dichloro-5H-pyrrolo[3,4-b]pyrazine-5,7(6H)-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.
