Description
CATO manufactures N4-(2,4-Dichlorophenyl)quinazoline-4,6-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.
N4-(2,4-Dichlorophenyl)quinazoline-4,6-diamine (CAS 1428063-66-4), molecular formula C14H10Cl2N4 and molecular weight 305.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N4-(2,4-Dichlorophenyl)quinazoline-4,6-diamine (C14H10Cl2N4) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
