Chemical Structure
Description
Methyl (2S)-3-(tert-butoxy)-2-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}propanoate (CAS 951324-28-0) is a high-purity analytical reference standard with the molecular formula C23H27NO5 and a molecular weight of 397.46 g/mol.
Methyl (2S)-3-(tert-butoxy)-2-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}propanoate (C23H27NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
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.
