Chemical Structure
Description
N4-(7-chloro-2-methylquinazolin-4-yl)-N1,N1-diethylpentane-1,4-diamine (CAS 57942-25-3) is a high-purity analytical reference standard with the molecular formula C18H27ClN4 and a molecular weight of 334.89 g/mol.
The molecular framework of N4-(7-chloro-2-methylquinazolin-4-yl)-N1,N1-diethylpentane-1,4-diamine (C18H27ClN4) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures N4-(7-chloro-2-methylquinazolin-4-yl)-N1,N1-diethylpentane-1,4-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.
