Isobutylmercaptan Chemical Properties,Usage,Production
Chemical Properties
2-Methyl-1-propanethiol has a cooked vegetable, almost mustard-like, odor
Chemical Properties
Liquid; unpleasant odor.
Occurrence
Reported found in guava, milk, cooked beef, cooked pork and beer.
Uses
Flammable, dangerous fire risk.
General Description
2-methyl-1-propanethiol attaches with L-Cys (the carrier) via a disulfide bond to form the brain-targeted drug delivery systems (BTDS).
Purification Methods
Dissolve the thiol in EtOH, and add to 0.25M Pb(OAc)2 in 50% aqueous EtOH. The precipitated lead mercaptide is filtered off, washed with a little EtOH, and impurities are removed from the molten salt by steam distillation. After cooling, dilute HCl is added dropwise to the residue, and the mercaptan is distilled directly from the flask. Water is separated from the distillate, and the mercaptan is dried (Na2CO3) and distilled under nitrogen.
