Description
CATO manufactures 2,2-Dimethyl-3-(p-tolyl)-2,3-dihydroquinazolin-4(1H)-one 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.
CATO supplies 2,2-Dimethyl-3-(p-tolyl)-2,3-dihydroquinazolin-4(1H)-one (CAS 568592-48-3), a certified reference material (molecular formula C17H18N2O, MW 266.34 g/mol) for analytical method development and quality control.
The molecular framework of 2,2-Dimethyl-3-(p-tolyl)-2,3-dihydroquinazolin-4(1H)-one (C17H18N2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
