Chemical Structure
Description
N-allyl-2-(4-chlorobenzyl)quinazolin-4-amine (CAS 303149-64-6) is a high-purity analytical reference standard with the molecular formula C18H16ClN3 and a molecular weight of 309.79 g/mol.
Based on its molecular formula C18H16ClN3, N-allyl-2-(4-chlorobenzyl)quinazolin-4-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 309.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures N-allyl-2-(4-chlorobenzyl)quinazolin-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.
