Chemical Structure
Description
The molecular framework of (2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-tetrahydropyran-4-yl-propanoic acid (C23H25NO5) 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).
(2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-tetrahydropyran-4-yl-propanoic acid (CAS 1879080-16-6), molecular formula C23H25NO5 and molecular weight 395.45 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
