Thenoyltrifluoroacetone Chemical Properties
Melting point 40-44 °C(lit.)
Boiling point 96-98 °C8 mm Hg(lit.)
density 1.4373 (estimate)
Fp 233 °F
storage temp. 2-8°C
solubility sparingly soluble in water, readily soluble in organic solvents. Distribution ratio between acidic water and benzene is about 40. In alkaline aqueous medium it exists in the enolate form, this being relatively more soluble in water. The equilibrium distribution ratio between benzene and alkaline aqueous medium (about pH 8) is about 1. In alkaline aqueous medium of pH > 9 TTA decomposes to trifluoroacetone and acetylthiophen.

Thenoyltrifluoroacetone Usage And Synthesis
DescriptionTTFA?(326-91-0) blocks the respiratory chain complex II causing inhibition of mitochondrial respiration.? Respiratory chain complex II inhibition is caused via binding of TTFA to two ubiquinone binding sites, Qp and Qd.1?Inhibition of Complex II by TFA has been shown to cause a delay in overall cell cycle progression leading to oxidative stress.2,3?TTFA also was found to inhibit porcine liver carboxylesterase (IC50?= 0.54 μM).4
Chemical Propertieslight yellow to beige to brown crystalline powder,
UsesThenoyltrifluoroacetone is one of the most proved extracting agents in solventextraction analysis. It is equally suitable for the separation and selective enrichment of metal ions.
2-Thenoyltrifluoroacetone (TTFA) is an inhibitor of respiration in animals and bacteria. In animals, TTFA binds at the quinone reduction site of succinate:ubiquinone oxidoreductase (SQR; Complex II), preventing ubiquinone from binding. It inhibits NADH fumarate reductase in bacteria. TTFA also inhibits photosystem II in plants and NADH-ubiquinone oxidoreductase of the virus Vibrio cholerae, decreasing cholera toxin production. This compound is also a chelator of metals, including lanthanum, zirconium, hafnium, and neodymium. Reagent for the determination of actinides and lanthanides.
2-Thenoyltrifluoroacetone is used for the extractive spectrophotometric determination of ruthenium at ph 4.0 (acetate buffer).
Thenoyltrifluoroacetone has also been used as an alternative β-diketone for in-house assay development since NTA was not, until recently, commercially available.
Uses2-Thenoyltrifluoroacetone is an inhibitor of respiration in animals and bacteria. TTFA binds at the quinone reduction site of succinate ubiquinone oxidoreductase.
Purification MethodsCrystallise the dione from hexane or *benzene. (Anaqueous solutions slowly decompose it). It has 1638(C=O), 1657(C=C)cm-1 . The oxime crystallises from H2O or aqueous EtOH. It is used for the determination of Actinides and Lanthanides. [Chaston et al. Aust J Chem 18 673 1956, Jeffrey et al.
