Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N-(((9H-Fluoren-9-yl)methoxy)carbonyl)-O-ethyl-L-threonine (CAS 2108708-74-1), a certified reference material (molecular formula C21H23NO5, MW 369.41 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H23NO5, N-(((9H-Fluoren-9-yl)methoxy)carbonyl)-O-ethyl-L-threonine contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 369.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
