High Purity DL-Dithiothreitol CAS 3483-12-3

DL-Dithiothreitol (described as DTT) is a little molecule organic lowering representative with the chemical formula C4H10O2S2.

DL-Dithiothreitol is a frequently used decreasing representative with solid reducibility, which is mostly because of the conformational stability of the six-membered ring (consisting of disulfide bonds) in its oxidation state.

The isomer of Dithiothreitol is dithioerythritol (DTE), the C3-epimer of DTT.

The lowering power is influenced by the pH value, as well as it can just play a minimizing effect when the pH value is higher than 7.

Because of the low nucleophilicity of protonated sulfur, as the pH value lowers, the efficient reducibility of DTT additionally lowers.

Tris(2-carboxyethyl)phosphine hydrochloride (TCEP hydrochloride) can be made use of as a substitute for DL-Dithiothreitol under reduced pH conditions, and it is additionally more secure than DTT.

This is due to the fact that only the deprotonated thiolate anions (-S–) are responsive, while mercaptans (-SH) do not; and also the pKa of sulfhydryl teams is typically ~ 8.3.
