Trifluoroacetic Acid
Trifluoroacetic acid is a corrosive organofluorine compound that is structurally analogous to, but stronger than, acetic acid. Available in various quantities and reagent grades, it is used in NMR spectroscopy, mass spectrometry, organic synthesis, etc.
Almost 100,000-fold more acidic than acetic acid, TFA is widely used in organic chemistry. TFA is used as a reagent in organic synthesis because of its properties: volatility, organic solvent solubility, and acidic strength. It is less oxidizing than sulfuric acid and is more readily available in its anhydrous form than some other acids . Other features include:
- Used in acid-catalyzed reactions, especially peptide synthesis (to cleave esters)
- Dissolves protein when mixed with liquid SO2
- Removes t-butyl derived side-chain protecting groups in Fmoc peptide synthesis
- Can remove the t-butoxycarbonyl protecting group in organic synthesis
- At low concentrations, acts as an ion-pairing agent for peptides and small proteins in organic compound liquid chromatography
- For acid-stable materials, can be a solvent for NMR spectroscopy
- Acts as a calibrant in mass spectrometry
- Used to produce trifluoroacetate salts
- An ingredient in adhesives, sealants, paints, and coatings
When TFA combines with bases and metals, especially light metals, a strong exothermic reaction occurs. When mixed with lithium aluminum hydride (LAH), the reaction is explosive.
Although nonflammable, TFA is corrosive to skin, eyes, and mucous membranes and requires careful use and handling. It is harmful when inhaled, causes severe skin burns and eye damage, and is toxic to aquatic organisms at even low concentrations.
TFA is also a product of the metabolic breakdown of the anesthetic agent halothane. It is the suspected cause of halothane-induced hepatitis.

Medchemexpress LLC GIP, rat TFA | 99.8% | 5002.58 | 5 MG
GIP, rat TFA is a bioactive peptide of rat origin, also known as glucose-dependent insulinotropic polypeptide or gastric inhibitory polypeptide. This 42-amino acid peptide is released by K cells in the duodenum and jejunum in response to food intake. GIP, along with GLP, stimulates insulin secretion from pancreatic beta cells and appears to promote beta cell proliferation and survival. Recent studies suggest a role for GIP in lipid homeostasis and a potential function in the pathogenesis of obesity.

Medchemexpress LLC DOTA-LM3 TFA | 99.3% | 1664.18 | 5 MG
DOTA-LM3 TFA is a somatostatin receptor (SSTR) antagonist. The LM3 component refers to p-Cl-Phe- cyclo(D-Cys-Tyr-D-4-amino-Phe(carbamoyl)-Lys-Thr-Cys)D-Tyr- NH2, which is also a somatostatin antagonist. This product is often isotopically labeled for in vivo tumor tracing, such as 177Lu-DOTA-LM3 TFA and 68Ga-DOTA-LM3 TFA. It can be used for the synthesis and research of Radionuclide-Drug Conjugates (RDCs).
- Acts as an antagonist for somatostatin receptors
- Commonly labeled with isotopes like 177Lu or 68Ga for in vivo tumor tracing
- 68Ga-DOTA-LM3 TFA exhibits favorable biodistribution
- Shows high tumor uptake and good tumor retention
- 68Ga-DOTA-LM3 TFA has few safety concerns
- Useful for research in DOTATOC-negative liver metastases, including pancreatic NET and extensive tumor thrombosis
- Can be utilized for the synthesis and research of Radionuclide-Drug Conjugates (RDCs)
