Bis[bis(trimethylsilyl)amino]difluorsilan, also known as bis[bis(trimethylsilyl)amino]difluorosilane, is a chemical compound with the formula [(Me3Si)2N]2SiF2. It is a colorless, crystalline solid that is sensitive to moisture and air. Bisdifluorsilan is a derivative of silicon, featuring two fluorine atoms and two nitrogen atoms bonded to a central silicon atom. The nitrogen atoms are each connected to two trimethylsilyl groups, which are alkyl groups consisting of three methyl groups attached to a silicon atom. Bis[bis(trimethylsilyl)amino]difluorsilan is an important precursor in the synthesis of various organosilicon compounds and is used in the production of specialty materials, such as silicones and silane coupling agents. Due to its reactivity, it is typically handled under an inert atmosphere or in a controlled environment to prevent unwanted side reactions.
The CAS Registry Mumber 1961-19-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,6 and 1 respectively; the second part has 2 digits, 1 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1961-19: (6*1)+(5*9)+(4*6)+(3*1)+(2*1)+(1*9)=89 89 % 10 = 9 So 1961-19-9 is a valid CAS Registry Number.
