Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-Chlorophenyl)-5-methyl-12-oxo-5H,5aH,6H,7H,8H,9H,10H,12H-azepino[2,1-b]quinazoline-3-carboxamide.
CATO supplies N-(4-Chlorophenyl)-5-methyl-12-oxo-5H,5aH,6H,7H,8H,9H,10H,12H-azepino[2,1-b]quinazoline-3-carboxamide (CAS 1775471-59-4), a certified reference material (molecular formula C21H22ClN3O2, MW 383.87 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-(4-Chlorophenyl)-5-methyl-12-oxo-5H,5aH,6H,7H,8H,9H,10H,12H-azepino[2,1-b]quinazoline-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 383.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures N-(4-Chlorophenyl)-5-methyl-12-oxo-5H,5aH,6H,7H,8H,9H,10H,12H-azepino[2,1-b]quinazoline-3-carboxamide 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.
