812-15-7 Usage
General Description
PENTAMETHYLDISILANE 97 is a clear, colorless liquid with a strong, pungent odor. It is commonly used as a reagent in organic synthesis and as a silicon source in the production of silicon-containing materials. It is also used as a surface modifier in coatings and as a precursor in the manufacture of electronic components and semiconductors. PENTAMETHYLDISILANE 97 is highly flammable and should be handled with caution, as it can react violently with water, acids, and oxidizing agents. It should be stored in a cool, well-ventilated area away from heat, sparks, and flames. Overall, PENTAMETHYLDISILANE 97 is a versatile chemical with a wide range of industrial applications.
Check Digit Verification of cas no
The CAS Registry Mumber 812-15-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 812-15:
(5*8)+(4*1)+(3*2)+(2*1)+(1*5)=57
57 % 10 = 7
So 812-15-7 is a valid CAS Registry Number.

Attempts to measure the kinetics of gas-phase insertion reactions of dimethylsilylene, generated by photolysis of dodecamethylcyclohexasilane, are described.Insertion of dimethylsilylene into silicon-hydrogen bonds was the main reaction with trimethylsilane, pentamethyldisilane, and sym-tetramethyldisilane; in all cases the activation energy for insertion was zero, and the rate constants were in the ratio of 1:3.1:4.3.Dimethylsilylene also inserted cleanly into hydrogen chloride with an activation energy of 28 kJ mol-1.Photochemical reactions with methylchlorosilanes were much more complex, involving little or no silylene chemistry; such reactions as did occur appeared to proceed almost entirely by radical mechanisms.
