Applicazioni

Sodium trichloroacetate, is used in acid binding reagent in the textile industry in the dying process. Sodium trichloroacetate has been reported previously to be an effective denaturation reagent for proteins was applied to poly(l-lysine) and poly(l-glutamic acid) to see its effects on a coil-to-helix transition and on the chemical reactivities of the ε-amino group of poly(l-lysine). Addition of sodium trichloroacetate to poly-(l-lysine) induced a helical conformation even at neutral pH where the ε-amino group of the polymer was protonated.

Note

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Stable under recommended storage conditions. Keep away from strong oxidizing agents. Hygroscopic.
