This compound is often used along with methanol and water in order to destain when using Coomassie Blue. In a common industrial reaction, this compound is reacted with ethylene and oxygen over a palladium catalyst, and the resulting product is then polymerized. Trifluorinating this compound produces a molecule often used to cleave t-Boc protecting groups in (*) solid-phase peptide synthesis. Rhodium and iridium catalysts

Trifluorinating this compound produces a molecule often used to cleave t-Boc protecting groups in (*) solid-phase peptide synthesis. Rhodium and iridium catalysts have historically been used in the production of this compound, which occurs through the reaction of carbon monoxide and methanol. Anhydrous versions of this compound can form crystals similar to ice and so are referred to as its glacial forms. After formic acid, this compound is the second simplest carboxylic acid. For 10 points, name this two-carbon acid found in vinegar.
