Chemical Structure
Description
The occurrence of 8-Aza-2,6-diaminopurine Sulfate (1:x) is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
8-Aza-2,6-diaminopurine Sulfate (1:x) (CAS 65591-11-9), molecular formula C4H5N7H2O4S and molecular weight 249.20 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H5N7H2O4S, 8-Aza-2,6-diaminopurine Sulfate (1:x) contains a carbohydrate-derived structure, an amide group, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 249.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
