Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-((((2-chlorobenzyl)oxy)carbonyl)amino)pentanoic acid (CAS 198561-86-3), a certified reference material (molecular formula C28H27ClN2O6, MW 522.98 g/mol) for analytical method development and quality control.
(S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-((((2-chlorobenzyl)oxy)carbonyl)amino)pentanoic acid (C28H27ClN2O6) 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.
