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.
N4-(3-Chlorophenyl)-6-methylpyrimidine-2,4-diamine (CAS 7781-33-1) is a high-purity analytical reference standard with the molecular formula C24H16O2 and a molecular weight of 336.38 g/mol.
The molecular framework of N4-(3-Chlorophenyl)-6-methylpyrimidine-2,4-diamine (C24H16O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures N4-(3-Chlorophenyl)-6-methylpyrimidine-2,4-diamine 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.
