TriphenylMethyl chloride

  • CAS:76-83-5
  • MW:278.7754
  • MF:C19H15Cl
TriphenylMethyl chloride, with the chemical formula C19H15Cl and CAS registry number 76-83-5, is a compound widely used as a protecting group in organic synthesis. This white crystalline solid, also known as Trityl chloride, is notable for its role in safeguarding sensitive functional groups during chemical reactions. Trityl Chloride is used in the preparation of S-trityl-L-cysteine (STLC), a tight-binding inhibitor of Eg5 that prevents mitotic progression. It serves as a key intermediate in the preparation of various organic compounds and is commonly employed in peptide synthesis and other organic transformations. TriphenylMethyl chloride plays a crucial role in organic chemistry, facilitating the synthesis of complex molecules by preventing unwanted reactions at specific sites. Its application extends to pharmaceuticals, agrochemicals, and materials science, where precise control over chemical reactions is essential for product synthesis and development. View more+

3. Use and Manufacturing
3.1 Description
TriphenylMethyl chloride (CAS 76-83-5) is a colorless to pale yellow liquid with a pungent odor. Its basic structure consists of a triphenylmethyl group attached to a chlorine atom. This chemical is insoluble in water but soluble in organic solvents such as ethanol and ether. It has a boiling point of 246-248°C and a melting point of -40°C.

Application
TriphenylMethyl chloride has various applications in different fields:

Pharmaceutical Industry: In the pharmaceutical industry, TriphenylMethyl chloride is used as a protecting group for alcohols and amines during organic synthesis. It acts as a temporary shield, preventing unwanted reactions from occurring at specific functional groups. The mechanism involves the formation of a stable covalent bond between the protecting group and the desired functional group, which can be easily removed later.

Chemical Research: TriphenylMethyl chloride is also utilized in chemical research as a reagent for the synthesis of various organic compounds. It can undergo substitution reactions with nucleophiles, leading to the introduction of the triphenylmethyl group into the target molecule. This allows for the modification of the compound's properties or the creation of new compounds.

Storage Conditions
Store in a cool, dry place.
3.2 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.
