Methiodide

In organic chemistry, a methiodide is a chemical derivative produced by the reaction of a compound with methyl iodide. Methiodides may be formed through the methylation of amines:

R3N + CH3I → (CH3)R3N+I−

Methiodides are generally prepared to alter chemical or pharmacological properties. Examples include:

  • Cocaine methiodide, a charged cocaine analog which cannot pass the blood brain barrier and enter the brain[1]
  • Bicuculline methiodide, a water-soluble form of bicuculline
