Chemical structure of 3-mercapto-3-methylbutan-1-ol

3-Mercapto-3-methylbutan-1-ol, abbreviated as MMB, is a thiol and an alcohol. MMB is a degradation product of felinine in cat urine and is a putative cat pheromone [1]. MMB was also found in Sauvignon blanc wines together with the related compounds 4-mercapto-4-methylpentan-2-ol and 3-mercaptohexan-1-ol [2].
