Chemical Structure
Description
The occurrence of N-(((9H-Fluoren-9-yl)methoxy)carbonyl)-N-methyl-D-methionine is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(((9H-Fluoren-9-yl)methoxy)carbonyl)-N-methyl-D-methionine (CAS 1932384-22-9), molecular formula C21H23NO4S and molecular weight 385.48 g/mol, is a CATO reference standard with documented purity and traceability.
N-(((9H-Fluoren-9-yl)methoxy)carbonyl)-N-methyl-D-methionine (C21H23NO4S) contains a flavonoid core, an amide group, a sulfone 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. 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.
