Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
7280-83-3 Purine, 2,6-diamino-, sulfate Purine-2,6-diyldiamine sulphate 9H-Purine-2,6-diamine, sulfate (1:?) 1H-Purine-2,6-diamine, sulfate 2-6 DP AI3-50438 2,6-Diaminopurine sulfate EINECS 230-697-9 (CAS 7280-83-3), molecular formula C5H6N6H2O4S and molecular weight 248.22 g/mol, is a CATO reference standard with documented purity and traceability.
7280-83-3 Purine, 2,6-diamino-, sulfate Purine-2,6-diyldiamine sulphate 9H-Purine-2,6-diamine, sulfate (1:?) 1H-Purine-2,6-diamine, sulfate 2-6 DP AI3-50438 2,6-Diaminopurine sulfate EINECS 230-697-9 (C5H6N6H2O4S) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
