Compared with other compounds in its class, the molecular weight of 434.19 g/mol gives 5-Chloro-N4-(cyclopropylmethyl)-2-methyl-N4-propyl-N6-(2,4,6-trichlorophenyl)pyrimidine-4,6-diamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Chloro-N4-(cyclopropylmethyl)-2-methyl-N4-propyl-N6-(2,4,6-trichlorophenyl)pyrimidine-4,6-diamine (CAS 184241-44-9), a certified reference material (molecular formula C18H20Cl4N4, MW 434.19 g/mol) for analytical method development and quality control.
Structurally, 5-Chloro-N4-(cyclopropylmethyl)-2-methyl-N4-propyl-N6-(2,4,6-trichlorophenyl)pyrimidine-4,6-diamine (C18H20Cl4N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 434.19 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
