Silicon tetraisocyanate is used as a building block in the synthesis of other silicon-based materials and polymers. Its reactivity allows for the formation of various silicon-containing compounds with unique properties, which can be utilized in different industries.
Used as a Crosslinking Agent in Resin and Polymer Production:
Silicon tetraisocyanate is used as a crosslinking agent in the production of certain resins and polymers. Its ability to form strong covalent bonds between polymer chains enhances the mechanical properties and durability of the final product.
Safety Precautions:
It is important to handle silicon tetraisocyanate with caution, as it is toxic and can cause severe irritation to the skin, eyes, and respiratory system. Appropriate safety measures, such as wearing protective gear and working in a well-ventilated area, should be taken when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 3410-77-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,1 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3410-77:
(6*3)+(5*4)+(4*1)+(3*0)+(2*7)+(1*7)=63
63 % 10 = 3
So 3410-77-3 is a valid CAS Registry Number.

Crystal structure and dimorphism of silicon tetraisocyanate Si(NCO) 4
Schmidt, Carsten Ludwig,Jansen, Martin
, p. 275 - 278 (2012/05/20)
Silicon tetraisocyanate Si(NCO)4 was obtained by reacting SiCl4 and AgNCO in boiling toluene. The colourless liquid was analyzed by Raman and NMR spectroscopy. Structural studies on solid Si(NCO) 4 (melting point: +26°C) have revealed it to exist in two polymorphic modifications. According to the results of single-crystal X-ray diffraction, at T = -173°C, α-Si(NCO)4 exhibits triclinic symmetry (Pβar{1}$; a = 10.05(5), b = 10.50(2), c = 14.32(1) A, α = 91.62(1)°, β = 92, 32(1)°, γ = 99.68(1)°; V = 1488.56(3) A3; Z = 8). Above T = -33°C, a monoclinic phase evolves, β-Si(NCO)4 (P21/c; a = 10.78(3), b = 7.11(1), c = 10.27(5) A, β = 99, 06(9)°; V = 777.39(1) A3; Z = 4). The charge distribution was studied for both polymorphs. In the solid state, Si(NCO)4 is a tetrahedral molecule with the Si-N=C=O linkages bent at the nitrogen atoms. Copyright

, (2008/06/13)
Optionally substituted silicon isocyanates are prepared by reacting a corresponding silicon halide with an alkali metal cyanate or an alkaline earth metal cyanate in an inert solvent having a dielectric constant below about 10, in the presence of a crown ether as a catalyst.
