(3-Chlorophenylethynyl)trimethylsilane
(3-Chlorophenylethynyl)trimethylsilane (CAS 227936-62-1), with the molecular formula ClC6H4C≡CSi(CH3)3 and a molecular weight of 208.76 g/mol, is a valuable organic building block. This halogenated hydrocarbon features an alkynyl group protected by a trimethylsilyl moiety, making it useful in various synthetic organic chemistry applications, particularly where controlled introduction of the 3-chlorophenylethynyl fragment is required. It is supplied by TSS at a minimum assay of 98%.
Organic Synthesis Intermediate
Serves as a versatile intermediate in complex organic syntheses. The trimethylsilyl group acts as a protecting group for the alkyne, allowing for selective reactions elsewhere in the molecule before deprotection and further functionalization of the ethynyl group.
Building Block for Specialty Chemicals
Utilised in the construction of more intricate molecular architectures, including potential pharmaceutical intermediates or materials science components. Its structure allows for elaboration via cross-coupling reactions or other alkyne chemistries.
Research and Development
A key reagent in research laboratories for exploring new synthetic pathways and developing novel compounds. Its defined structure and reactivity profile support academic and industrial R&D efforts.
