Chemical Structure
Description
The occurrence of 4-N-[(4-chlorophenyl)methyl]quinazoline-2,4-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-N-[(4-chlorophenyl)methyl]quinazoline-2,4-diamine (CAS 1509890-90-7), a certified reference material (molecular formula C15H13ClN4, MW 284.74 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H13ClN4, 4-N-[(4-chlorophenyl)methyl]quinazoline-2,4-diamine 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 284.74 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
