tert-Butyl(4-chlorobutoxy)dimethylsilane
tert-Butyl(4-chlorobutoxy)dimethylsilane (CAS: 89031-83-4), with the molecular formula Cl(CH2)4OSi(CH3)2C(CH3)3 and a molecular weight of 222.83 g/mol, is a valuable organosilicon compound. It functions as a protected alcohol, featuring a chlorobutyl ether moiety. This compound is primarily utilised as a building block in organic synthesis, particularly in the preparation of more complex molecules within the pharmaceutical and chemical industries.
Organic Synthesis Intermediate
This silane derivative serves as a versatile intermediate in organic synthesis. The tert-butyldimethylsilyl (TBDMS) ether group protects the alcohol functionality, allowing for selective reactions elsewhere in the molecule. The terminal chloride provides a reactive site for nucleophilic substitution or Grignard reagent formation.
Building Block for Pharmaceuticals
Its structure makes it useful in the multi-step synthesis of active pharmaceutical ingredients (APIs). The combination of a protected alcohol and a reactive alkyl halide allows for its incorporation into complex molecular architectures.
Research and Development
Primarily used in R&D laboratories for exploring new synthetic routes and developing novel chemical entities. It is a key component for chemists requiring a functionalised silane with both protecting and reactive groups.
