Cypionic acid is a carboxylic acid that has two isomers, namely alpha-cypionic acid and beta-cypionic acid. It is also known by other names, including 4-methylhexanoic acid, isocaproic acid, and alpha-methyl-n-valeric acid. These terms are often used interchangeably with cypionic acid, although each has a slightly different chemical structure. Another synonym for cypionic acid is 6-Heptenoic acid, which also has the same molecular formula. These synonyms are useful for scientists and researchers who are studying this compound's properties, chemical reactions, and potential applications. By using multiple names for this acid, researchers can access a wider range of literature and data about its properties and applications.
