Description
3-[(3-Chloro-4-methoxyphenyl)methyl]-2-{[(2,5-dimethylphenyl)methyl]sulfanyl}-6,7-dimethoxy-3,4-dihydroquinazolin-4-imine (CAS 439121-07-0), molecular formula C27H28ClN3O3S and molecular weight 510.05 g/mol, is a CATO reference standard with documented purity and traceability.
3-[(3-Chloro-4-methoxyphenyl)methyl]-2-{[(2,5-dimethylphenyl)methyl]sulfanyl}-6,7-dimethoxy-3,4-dihydroquinazolin-4-imine (C27H28ClN3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 3-[(3-Chloro-4-methoxyphenyl)methyl]-2-{[(2,5-dimethylphenyl)methyl]sulfanyl}-6,7-dimethoxy-3,4-dihydroquinazolin-4-imine 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.
