Chemical Structure
Description
3,7-Dimethyl-2,6-dioxo-2,3,6,7-tetrahydro-1h-purine-8-carbaldehyde (CAS 4921-54-4), molecular formula C8H8N4O3 and molecular weight 208.17 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H8N4O3, 3,7-Dimethyl-2,6-dioxo-2,3,6,7-tetrahydro-1h-purine-8-carbaldehyde contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 208.17 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.
