Applications

It finds its application in the reaction of the dilithio-derivative with an aldehyde, followed by conversion to the episulfide by reaction with ethyl chloroformate, and desulfurization with triethyl phosphite, leads to the (E)-2-alkenoic acid with high stereoselectivity. It is used as depilatories, hair straightening agent, hair waving agent, and reducing agent in cosmetic industry.

Notes

Air sensitive. Store away from oxidizing agents and air. Keep the container tightly closed and place it in a cool, dry and well ventilated condition. Protect from electrostatic charges and store away from ignition sources. Store under inert gas.
