Chemical Structure
Description
The occurrence of 3-Carbamoyl-2-({[(9H-fluoren-9-yl)methoxy]carbonyl}amino)propanoic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Carbamoyl-2-({[(9H-fluoren-9-yl)methoxy]carbonyl}amino)propanoic acid (CAS 157355-73-2) is a high-purity analytical reference standard with the molecular formula C19H18N2O5 and a molecular weight of 354.36 g/mol.
3-Carbamoyl-2-({[(9H-fluoren-9-yl)methoxy]carbonyl}amino)propanoic acid (C19H18N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
