CAS 156072-86-5: 2-Pyridinecarbonitrile,5-bromo-3-methyl-

5-Bromo-3-methylpyridine-2-carbonitrile

5-Bromo-3-methylpicolinonitrile is a synthetic compound that is used in the synthesis of formic acid. It is a colorless liquid with an odor similar to acetic acid. 5-Bromo-3-methylpicolinonitrile is synthesized by coupling two molecules of formaldehyde and then deprotecting the bromine group to produce formic acid. Formic acid has been used as a solvent, dye, and preservative in foods, pharmaceuticals, and textiles. It has also been used as an insecticide and herbicide. 5-Bromo-3-methylpicolinonitrile has shown toxicity to aquatic organisms, but it does not bioaccumulate significantly in the environment.
