Chemical Structure
Description
CATO supplies 7,9-Dihydro-1H-purine-2,6,8(3H)-trione, potassium salt (CAS 7000-30-8), a certified reference material (molecular formula C5H4N4O3K, MW 207.21 g/mol) for analytical method development and quality control.
The molecular framework of 7,9-Dihydro-1H-purine-2,6,8(3H)-trione, potassium salt (C5H4N4O3K) 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 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.
CATO manufactures 7,9-Dihydro-1H-purine-2,6,8(3H)-trione, potassium salt 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.
