CATO supplies 34171-43-2 Pyrimidine, 2-chloro-4-(dimethylamino)-5-methyl- 5-25-10-00196 (Beilstein Handbook Reference) BRN 0608293 4-Pyrimidinamine, 2-chloro-N,N,5-trimethyl- (CAS 34171-43-2), a certified reference material (molecular formula C7H10ClN3, MW 171.63 g/mol) for analytical method development and quality control.

The molecular framework of 34171-43-2 Pyrimidine, 2-chloro-4-(dimethylamino)-5-methyl- 5-25-10-00196 (Beilstein Handbook Reference) BRN 0608293 4-Pyrimidinamine, 2-chloro-N,N,5-trimethyl- (C7H10ClN3) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
