Chemical Structure
Description
The occurrence of 6-Imino-1-methyl-1,6-dihydropyrimidine-2,4-diamine is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Imino-1-methyl-1,6-dihydropyrimidine-2,4-diamine (CAS 749798-75-2) is a high-purity analytical reference standard with the molecular formula C5H9N5 and a molecular weight of 139.16 g/mol.
Based on its molecular formula C5H9N5, 6-Imino-1-methyl-1,6-dihydropyrimidine-2,4-diamine contains a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 139.16 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.
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.
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.
