China and Germany are the leading exporters of Chlorotrimethylsilane (CAS 75-77-4), collectively accounting for over half of global export value in recent years, while the United States, South Korea, and Japan represent the largest importers. Import volumes into Asia-Pacific markets have grown steadily since 2022, coinciding with moderate upward pressure on Chlorotrimethylsilane prices amid tightening supply from key European producers.
Chlorotrimethylsilane is a colorless, volatile liquid with a pungent, chlorinous odor. It is an organosilicon compound and a reactive chlorosilane, boiling at 57 °C and solidifying below −55 °C. It serves primarily as a silylating agent and key intermediate in the synthesis of silicon-based chemicals, including siloxanes, silicone polymers, and specialty silanes. Its principal applications are in the production of silicone resins, release coatings, and surface modifiers for electronics and medical devices, as well as in pharmaceutical and agrochemical synthesis where controlled silylation is required.
Chlorotrimethylsilane is a typical Silane Blocking Agent, which can protect or deprotect functional groups selectively. It is widely used in the syntheses of drugs. It have been used in the preparation of volatile derivatives of a wide range of compounds for GC analysis, and used for silylation and as a protection group in the process of various organic synthesis.
A clear, colorless, caustic and highly flammable liquid with a pungent odour. Readily hydrolyzed with liberation of hydrogen chloride; soluble in benzene, ether and perchloroethylene.
