Chemical Structure
Description
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.
2,8-Dichloro-1,9-dihydro-6H-purin-6-one (CAS 53225-79-9), molecular formula C5H2Cl2N4O and molecular weight 205.00 g/mol, is a CATO reference standard with documented purity and traceability.
2,8-Dichloro-1,9-dihydro-6H-purin-6-one (C5H2Cl2N4O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
As a certified reference material (CRM), 2,8-Dichloro-1,9-dihydro-6H-purin-6-one 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.
