pyridinium trifluoromethanesulfonate

Description:

Pyridinium trifluoromethanesulfonate, with the CAS number 52193-54-1, is an organic compound that serves as a versatile reagent in organic synthesis. It is characterized by its pyridinium cation, which is a positively charged nitrogen-containing heterocycle, and the trifluoromethanesulfonate anion, known for its strong electrophilic properties. This compound is typically a white to light yellow solid and is soluble in polar organic solvents, making it useful in various chemical reactions, particularly in the activation of alcohols and the promotion of nucleophilic substitutions. Its strong acidity and ability to stabilize transition states make it an effective catalyst in reactions such as acylation and alkylation. Additionally, pyridinium trifluoromethanesulfonate is valued for its low toxicity and ease of handling compared to other strong acids. However, it should be handled with care due to its corrosive nature and potential environmental impact. Overall, it is a valuable tool in synthetic organic chemistry, facilitating the formation of complex molecules.

Pyridinium trifluoromethanesulfonate

CAS: 52193-54-1

Pyridinium trifluoromethanesulfonate is a pyridinium salt with a hydroxyl group that binds to galacturonic acid. It is used in the synthesis of polysaccharides, such as chitosan and cellulose. Pyridinium trifluoromethanesulfonate is a cross-linking agent that forms covalent bonds between two molecules by reacting with the carbonyl groups in one molecule and the hydrogen bond in another. The binding constants for pyridinium trifluoromethanesulfonate are 1.4 x 10 M-1 for carboxylic acids, 2.2 x 10 M-1 for alcohols, and 4.3 x 10 M-1 for amines. The transport properties of this chemical are not well understood because it does not dissolve in water or organic solvents.
