Tris(2-methylpropyl)phosphane oxide, also known as trimethylpropyl phosphine oxide or TMPO, is an organophosphorus compound with the chemical formula C9H21O2P. It is a colorless, viscous liquid that is soluble in organic solvents and has a molecular weight of 200.24 g/mol. TMPO is primarily used as a stabilizer for various chemicals, including peroxides and hydroperoxides, due to its ability to decompose these compounds safely and effectively. It is also employed as an antioxidant and a flame retardant in the plastics and rubber industries. Additionally, TMPO has applications in the synthesis of other organophosphorus compounds and as a catalyst in certain chemical reactions.

7682-87-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7682-87-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,8 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7682-87:
(6*7)+(5*6)+(4*8)+(3*2)+(2*8)+(1*7)=133
133 % 10 = 3
So 7682-87-3 is a valid CAS Registry Number.
