Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 196.16 g/mol gives Dimethyl Pyrazine-2,5-dicarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dimethyl Pyrazine-2,5-dicarboxylate (CAS 13051-89-3) is a high-purity analytical reference standard with the molecular formula C8H8N2O4 and a molecular weight of 196.16 g/mol.
The molecular framework of Dimethyl Pyrazine-2,5-dicarboxylate (C8H8N2O4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Dimethyl Pyrazine-2,5-dicarboxylate 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.
