Chlorocyclohexyldimethylsilane
Chlorocyclohexyldimethylsilane (CAS 71864-47-6), with the molecular formula C6H11Si(CH3)2Cl and a molecular weight of 176.76 g/mol, is a silicon-based organosilicon compound. It serves as a valuable reagent in chemical synthesis, particularly in protection and derivatization strategies. Supplied by Tech Serve Solutions at a minimum purity of 98%, it is a key intermediate for research and industrial applications.

Protecting Group Chemistry
Chlorocyclohexyldimethylsilane can be employed in organic synthesis to introduce a silyl protecting group onto reactive functionalities such as alcohols or amines, facilitating multi-step syntheses by temporarily masking sensitive sites.
Derivatization Reagent
Its structure makes it suitable for derivatizing molecules, often to enhance their volatility or detectability in analytical techniques like gas chromatography-mass spectrometry (GC-MS).
Intermediate in Organosilicon Synthesis
This compound can act as a building block for the synthesis of more complex organosilicon compounds with tailored properties for materials science or specialized chemical applications.
