Chemical Structure
Description
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.
N-Ethyl-1,2-dimethyl-6-(methylimino)-N-phenyl-1,6-dihydropyrimidin-4-amine (CAS 133060-80-7), molecular formula C15H21N4Cl and molecular weight 292.81 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-Ethyl-1,2-dimethyl-6-(methylimino)-N-phenyl-1,6-dihydropyrimidin-4-amine (C15H21N4Cl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures N-Ethyl-1,2-dimethyl-6-(methylimino)-N-phenyl-1,6-dihydropyrimidin-4-amine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
