Heptafluoropropylselenosilane, with the chemical formula C3F7SeSi, is a colorless, volatile liquid that belongs to the class of organosilicon compounds. It is composed of a silicon atom bonded to a heptafluoropropylseleno group (CF2CF2CF2Se), which consists of three fluorinated ethylene units attached to a selenium atom. heptafluoropropylselenosilane is primarily used as a precursor in the synthesis of various organosilicon materials, such as polymers, resins, and elastomers, due to its unique properties, including thermal stability and chemical reactivity. The presence of fluorine atoms in the molecule imparts exceptional resistance to heat, oxidation, and aggressive chemicals, making heptafluoropropylselenosilane a valuable component in the development of high-performance materials for aerospace, electronics, and other advanced industries.
The CAS Registry Mumber 1647-59-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 7 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1647-59: (6*1)+(5*6)+(4*4)+(3*7)+(2*5)+(1*9)=92 92 % 10 = 2 So 1647-59-2 is a valid CAS Registry Number.
