Chemical Structure
Description
(2S,4R)-1-(((9H-fluoren-9-yl)methoxy)carbonyl)-4-(trifluoromethyl)azetidine-2-carboxylic acid (CAS 2387566-99-4), molecular formula C20H16F3NO4 and molecular weight 391.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2S,4R)-1-(((9H-fluoren-9-yl)methoxy)carbonyl)-4-(trifluoromethyl)azetidine-2-carboxylic acid (C20H16F3NO4) 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 391.34 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
