CATO supplies Racemic-(2R,3aR,6aR)-tert-butyl 2-((((benzyloxy)carbonyl)amino)methyl)tetrahydro-2h-furo[2,3-c]pyrrole-5(3H)-carboxylate (CAS 1445951-20-1), a certified reference material (molecular formula C20H28N2O5, MW 376.45 g/mol) for analytical method development and quality control.
The molecular framework of Racemic-(2R,3aR,6aR)-tert-butyl 2-((((benzyloxy)carbonyl)amino)methyl)tetrahydro-2h-furo[2,3-c]pyrrole-5(3H)-carboxylate (C20H28N2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
