Beschreibung

General description

Sodium tartrate dibasic dihydrate (L-(+)-Tartaric acid disodium salt, Sodium-L-tartrate dibasic dihydrate) is the sodium salt of tartaric acid. Mixtures of dimethyl sulfoxide and 1% aqueous solution of sodium-L-tartrate dibasic dihydrate have been employed for the resolution of various quaternary ammonium surfactants.

Application

Sodium tartrate dibasic dihydrate (L-(+)-Tartaric acid disodium salt, Sodium-L-tartrate dibasic dihydrate) may be used for the growth of crystals of xylanase C (XynC) from Gram-positive bacterium Bacillus subtilis.[1] It may be used to compose the reservoir solution for the growth of crystals of PcpR (a LysR-type transcription factor from Sphingobium chlorophenolicum L-1).[2]
