API Description: 1,1'-Methylenebis(4-((hydroxyimino)methyl)pyridinium) dimethanesulfonate (MMB-4 DMS) is used as a nerve agent antidote, particularly against organophosphorus compounds like sarin or VX. It works by reactivating acetylcholinesterase, an enzyme inhibited by nerve agents. MMB-4 DMS is considered a broad-spectrum oxime, offering improved efficacy over older treatments like 2-PAM.
