Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Chloro-2-(cyclohexyl(methyl)amino)quinazolin-4(3H)-one.
6-Chloro-2-(cyclohexyl(methyl)amino)quinazolin-4(3H)-one (CAS 1956355-99-9) is a high-purity analytical reference standard with the molecular formula C15H18ClN3O and a molecular weight of 291.78 g/mol.
6-Chloro-2-(cyclohexyl(methyl)amino)quinazolin-4(3H)-one (C15H18ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
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.
