Description
CATO supplies N2-(4-aminophenyl)-N4,N4,6-trimethylpyrimidine-2,4-diamine (CAS 1395786-40-9), a certified reference material (molecular formula C13H17N5, MW 243.31 g/mol) for analytical method development and quality control.
Structurally, N2-(4-aminophenyl)-N4,N4,6-trimethylpyrimidine-2,4-diamine (C13H17N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 243.31 g/mol, it falls into the medium-molecular-weight range. 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.
