Chemical Structure

7-N-methyl-[1,3]diazino[4,5-d]pyrimidine-2,4,7-triamine CAS 120641-13-6 chemical structure

Description

Based on its molecular formula C7H9N7, 7-N-methyl-[1,3]diazino[4,5-d]pyrimidine-2,4,7-triamine contains a nitrile group, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 191.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

7-N-methyl-[1,3]diazino[4,5-d]pyrimidine-2,4,7-triamine (CAS 120641-13-6) is a high-purity analytical reference standard with the molecular formula C7H9N7 and a molecular weight of 191.19 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.

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.
