2-METHYL-5-VINYLPYRIDINIUM SALTS

Disclosed are novel salts of 2-methyl-5-vinylpyridine (MVP), such as hydrogentartrates, bromide, and dihydrogenphosphate. In contrast to the free base, these salts are crystalline and stable and can be safely stored and transported. The salts can also be used to purify MVP, in particular to reduce its content of 5-ethyl-2-methylpyridine and unwanted isomers.
