[Chemical Properties]

White to yellow solid
[Uses]

amine, alcohol, thiol protecting reagent
[Uses]

Efficient method of tritylation of sensitive compounds and their subsequent detritylation
[Uses]

Trityl Chloride is an alkyl halide commonly used in organic synthesis to introduce the trityl protecting group. Trityl Chloride is used in the preparation of S-trityl-L-cysteine (STLC), a tight-bindin g inhibitor of Eg5 that prevents mitotic progression.
[Purification Methods]

Crystallise trityl chloride from iso-octane. Also crystallise it from 5 parts of pet ether (b 90-100o) and 1 part of acetyl chloride using 1.8g of solvent per g of chloride. Dry it in a desiccator over soda lime and paraffin wax. [Bachman Org Synth Coll Vol III 841 1955, Thomas & Rochow J Am Chem Soc 79 1843 1957, Moisel et al.
