Dithiobutylamine Hydrochloride is a water-soluble compound known for its strong disulfide-reducing properties. It capabable of reducing the enzyme papainn which has a relatively anionic active site. It serves as an effective alternative to DTT, offering faster and more potent reduction at lower pH levels. This non-volatile and almost odorless solid can be synthesized from L-aspartic acid.
