Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 357.38 g/mol gives Fmoc-3-fluoro-DL-valine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Fmoc-3-fluoro-DL-valine (CAS 1219144-82-7), a certified reference material (molecular formula C20H20FNO4, MW 357.38 g/mol) for analytical method development and quality control.
Structurally, Fmoc-3-fluoro-DL-valine (C20H20FNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 357.38 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
