(2R)-5-{[(tert-butoxy)carbonyl]amino}-2-{[(prop-2-en-1-yloxy)carbonyl]amino}pentanoic acid; dicyclohexylamine (CAS 947401-26-5), molecular formula C14H24N2O6C12H23N and molecular weight 497.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2R)-5-{[(tert-butoxy)carbonyl]amino}-2-{[(prop-2-en-1-yloxy)carbonyl]amino}pentanoic acid; dicyclohexylamine (C14H24N2O6C12H23N) is characterized by a steroid 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.
