3-((4-Chlorophenyl)(phenyl)methyl)-1-methyl-1,2,5,6-tetrahydro-1,2,4-triazine (CAS 22756-36-1) is a high-purity analytical reference standard with the molecular formula C17H18ClN3 and a molecular weight of 299.80 g/mol.
Based on its molecular formula C17H18ClN3, 3-((4-Chlorophenyl)(phenyl)methyl)-1-methyl-1,2,5,6-tetrahydro-1,2,4-triazine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 299.80 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.
