Dithiobutylamine

Dithiobutylamine (DTBA) is a reducing agent intended as an alternative for DTT in biochemical uses. It was designed to be easily synthesized in non-racemic form, to have a lower pKa (allowing more effective reduction at neutral pH), and to have a low disulfide E°′ reduction potential.^[1] It was rationally designed & reported in 2012.^[1] It is commercially available.
