Uses
Used in Chemical Synthesis:
1,3-DIPHENYL-1,1,3,3-TETRAMETHYLDISILAZANE is used as a starting material for the synthesis of its substitution products with the tetrachlorides of silicon and tin. This allows for the creation of new compounds with tailored properties for specific applications.
Used in Pharmaceutical Industry:
1,3-DIPHENYL-1,1,3,3-TETRAMETHYLDISILAZANE is used to prepare Cu-, Zn-, and H2-phthalocyanines using phthalimide. Phthalocyanines are a class of compounds with unique photophysical and photochemical properties, which have potential applications in photodynamic therapy, imaging, and as catalysts.
Used in Analytical Chemistry:
1,3-DIPHENYL-1,1,3,3-TETRAMETHYLDISILAZANE is used as a pre-column deactivation agent prior to the determination of fatty acids by GC-MS. This application helps to prevent unwanted interactions between the sample and the column, leading to improved separation and detection of fatty acids in the analysis.
Check Digit Verification of cas no
The CAS Registry Mumber 3449-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3449-26:
(6*3)+(5*4)+(4*4)+(3*9)+(2*2)+(1*6)=91
91 % 10 = 1
So 3449-26-1 is a valid CAS Registry Number.

supporting information, p. 8420 - 8423 (2013/09/02)
Support structure: In the presence of gold nanoparticles supported on alumina (Au/Al2O3), various hydrosilanes can be converted into the corresponding silyl isocyanates using urea as an isocyanate source. The observed catalysis is truly heterogeneous, and the retrieved Au/Al 2O3 catalyst can be reused several times without any loss of its high catalytic performance. Copyright
