Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium 5,6-dicarboxypyrazine-2,3-dicarboxylate.
Potassium 5,6-dicarboxypyrazine-2,3-dicarboxylate (CAS 54722-63-3) is a high-purity analytical reference standard with the molecular formula C8H4N2O8K and a molecular weight of 295.22 g/mol.
The molecular framework of Potassium 5,6-dicarboxypyrazine-2,3-dicarboxylate (C8H4N2O8K) is characterized by a carbohydrate-derived structure, an amide group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures Potassium 5,6-dicarboxypyrazine-2,3-dicarboxylate 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.
