Melting point: −122 °C (−188 °F; 151 K) Boiling point: ... Dichlorosilane, or DCS as it is commonly known, is a chemical compound with the formula H 2 SiCl 2.
Melting point: −76 °C (−105 °F; 197 K) Boiling point: 70 °C (158 °F; 343 K) ... Diverse types of dichlorosilane precursors, such as Ph 2 SiCl 2, ...
Silicon tetrachloride and trichlorosilane are intermediates in the production of ultrapure silicon in the semiconductor industry. Chlorosilanes obtained from crude silicon are purified by fractional distillation techniques and then reduced with hydrogen to give silicon of 99.999 999 999 % purity.
Via hydrosilylation, trichlorosilane is a precursor to other useful organosilicon compounds: . RCH=CH 2 + HSiCl 3 → RCH 2 CH 2 SiCl 3. Some useful products of this or similar reactions include octadecyltrichlorosilane (OTS), perfluoroctyltrichlorosilane (PFOTCS), and perfluorodecyltrichlorosilane (FDTS).

Methyltrichlorosilane undergoes hydrolysis, shown in idealized form here: [1] MeSiCl 3 + 3 H 2 O → MeSi(OH) 3 + 3 HCl. The silanol is unstable and will eventually condense to give a polymer network:
