Description
CATO supplies 7-Chloro-2-(4-phenylpiperazin-1-yl)quinazolin-4(1H)-one (CAS 61741-64-8), a certified reference material (molecular formula C18H17ClN4O, MW 340.81 g/mol) for analytical method development and quality control.
Structurally, 7-Chloro-2-(4-phenylpiperazin-1-yl)quinazolin-4(1H)-one (C18H17ClN4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 340.81 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
