N-(3-Chloro-7-nitro-9-oxo-9H-fluoren-2-yl)-2,2,2-trifluoroacetamide CAS 4083-50-5

Description

The occurrence of N-(3-Chloro-7-nitro-9-oxo-9H-fluoren-2-yl)-2,2,2-trifluoroacetamide is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-(3-Chloro-7-nitro-9-oxo-9H-fluoren-2-yl)-2,2,2-trifluoroacetamide (CAS 4083-50-5), molecular formula C15H6ClF3N2O4 and molecular weight 370.67 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, N-(3-Chloro-7-nitro-9-oxo-9H-fluoren-2-yl)-2,2,2-trifluoroacetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 370.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
