Application
Ethyl trifluoroacetate can be used:
- To synthesize cyclopentenones or furans containing trifluoromethyl group from aromatic ynones.
- In the selective trifluoroacetylation of anilines catalyzed by 4-dimethylaminopyridine.
- As a starting material in the two-step electrosynthesis of trifluoroacetyltrimethylsilane (CF3COSiMe3).
- In the preparation of trifluoromethyl ketones via trifluoroacetic ester/ketone metathesis with alkyl aryl ketones.
- To synthesize o-fluorinated trifluoro acetophenones from substituted fluorobenzene.

Targeting cyclooxygenase-2 (COX-2) for molecular imaging is an attractive approach applicable for its overexpression in inflammation and many malignancies. Herein, for monitoring COX-2, we synthesize a specific COX-2 probe celecoxib-MPA probe (CMP), based on celecoxib and a water-soluble near-infrared dye
