Chemical Structure
Description
The molecular framework of 2,6-Diaminopyrimidine-4-thiol sulfate (C4H6N4SH2O4S) 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).
2,6-Diaminopyrimidine-4-thiol sulfate (CAS 307496-37-3) is a high-purity analytical reference standard with the molecular formula C4H6N4SH2O4S and a molecular weight of 240.25 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,6-Diaminopyrimidine-4-thiol sulfate 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.
