Dithiothreitol

• English name: Dithiothreitol
• Abbreviation: DTT
• Chemical formula: C₄H₁₀O₂S₂
• CAS: 3483-12-3
• Usage: Dithiothreitol is a small molecule organic reducing agent. In its reduced state, it is a linear molecule that, after oxidation, becomes a hexagonal cyclic structure containing disulfide bonds. The name dithiothreitol is derived from threose (a four carbon monosaccharide). The isomer of DTT is dithioerythritol (DTE), which is the C3 epimer of DTT.
