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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
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.
Solubility
Solubility in hot acetic acid is almost transparent.
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.
