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.
2,6-Diaminopurine Hemisulfate Hydrate (CAS 116295-72-8), molecular formula C5H6N6H2O4SH2O and molecular weight 266.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Diaminopurine Hemisulfate Hydrate (C5H6N6H2O4SH2O) is characterized by a carbohydrate-derived structure, an amide group, a sulfone 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. 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).
As a certified reference material (CRM), 2,6-Diaminopurine Hemisulfate Hydrate 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.
