Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(1R,3r)-1-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-fluorocyclobutane-1-carboxylic acid (CAS 2137066-14-7) is a high-purity analytical reference standard with the molecular formula C20H18FNO4 and a molecular weight of 355.36 g/mol.
Structurally, (1R,3r)-1-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-fluorocyclobutane-1-carboxylic acid (C20H18FNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 355.36 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.
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.
