Hydrazine, 1,1-dimethyl-2,2-bis(trimethylsilyl)-, also known as 1,1-dimethyl-2,2-bis(trimethylsilyl)hydrazine or bis(trimethylsilyl)methylhydrazine, is a colorless, volatile, and highly reactive liquid with the chemical formula C8H22N2Si2. It is a derivative of hydrazine, where two of the hydrogen atoms are replaced by trimethylsilyl groups. Hydrazine, 1,1-dimethyl-2,2-bis(trimethylsilyl)- is used as a reagent in organic synthesis, particularly in the preparation of various organosilicon compounds and as a precursor for the synthesis of other silyl-protected hydrazines. Due to its high reactivity and potential toxicity, it is essential to handle this chemical with proper safety precautions and in a controlled environment.
The CAS Registry Mumber 684-26-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 4 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 684-26: (5*6)+(4*8)+(3*4)+(2*2)+(1*6)=84 84 % 10 = 4 So 684-26-4 is a valid CAS Registry Number.
