Applications

It is considered as a more reactive reagent than Chlorotriphenyl­methane, for the preparation of trityl esters. It is also used in one-pot conversion of amino acids to their N-trityl derivatives involving N,O-ditritylation and selective methanolysis of the trityl ester.

Notes

Moisture sensitive. Store away from oxidizing agents and bases. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.
