Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-Chloro-6-methoxy-7-(3-(4-methylpiperazin-1-yl)propoxy)quinazoline (CAS 264208-55-1), molecular formula C17H23ClN4O2 and molecular weight 350.84 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-6-methoxy-7-(3-(4-methylpiperazin-1-yl)propoxy)quinazoline (C17H23ClN4O2) contains a steroid core, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
