Process for the purification of a salt of clavulanic acid |
abstract |
A process in which a salt of clavulanic acid, typically an amine salt or an alkali metal salt is exposed to conditions, particularly a pH of less than 6.0, which reduces the quantity of contaminating impurities. The process may be a washing process, a recrystallisation process or a preparative process. |
