Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 6,7-Dimethoxy-3-phenethyl-2-((pyridin-4-ylmethyl)thio)quinazolin-4(3H)-imine (CAS 691858-07-8), a certified reference material (molecular formula C24H24N4O2S, MW 432.54 g/mol) for analytical method development and quality control.
6,7-Dimethoxy-3-phenethyl-2-((pyridin-4-ylmethyl)thio)quinazolin-4(3H)-imine (C24H24N4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
