Chemical Structure
Description
Structurally, (2-Amino-4-oxo-3,4,7,8-tetrahydropteridin-6-yl)methyl trihydrogen diphosphate (C7H11N5O8P2) contains a carbohydrate-derived structure, an amide group, a phosphate ester group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 355.14 g/mol, it falls into the moderately-high-molecular-weight range. 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-Amino-4-oxo-3,4,7,8-tetrahydropteridin-6-yl)methyl trihydrogen diphosphate (CAS 3545-84-4), molecular formula C7H11N5O8P2 and molecular weight 355.14 g/mol, is a CATO reference standard with documented purity and traceability.
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.
