1,4,5,6-Tetrahydropyrimidine hydrochloride (CAS 38115-29-6) is a high-purity analytical reference standard with the molecular formula C4H8N2HCl and a molecular weight of 120.58 g/mol.
Based on its molecular formula C4H8N2HCl, 1,4,5,6-Tetrahydropyrimidine hydrochloride contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 120.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
