Stannane, hydroxytris(2-methyl-2-phenylpropyl)-, also known as hydroxytris(2-methyl-2-phenylpropyl)stannane or (2-methyl-2-phenylpropyl)3SnOH, is an organotin compound characterized by a central tin (Sn) atom bonded to three 2-methyl-2-phenylpropyl ligands and one hydroxyl (OH) group. Stannane, hydroxytris(2-methyl-2-phenylpropyl)- is a colorless liquid with a molecular formula of C27H37OSn and a molecular weight of 505.23 g/mol. It is primarily used as a catalyst in various chemical reactions, particularly in the production of polyurethane foams and as a stabilizer for PVC. Due to its potential toxicity and environmental impact, the use of organotin compounds like this is subject to strict regulations in many countries.

1178-81-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1178-81-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,7 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1178-81:
(6*1)+(5*1)+(4*7)+(3*8)+(2*8)+(1*1)=80
80 % 10 = 0
So 1178-81-0 is a valid CAS Registry Number.

STERIC EFFECTS IN NEOPHILTIN(IV) CHEMISTRY

Lockhart, Thomas P.

, p. 179 - 186 (2007/10/02)

The stability and self-association in solution of (neophyl3Sn)2O, neophyl3SnOH, and (neophyl3Sn)2CO3 (neophyl = C6H5(CH3)2CCH2) have been examined by 119Sn NMR.The presence of Sn,Sn spin coupling through oxygen (2J(119Sn,117Sn)) has been used to distinguish between the distannoxane and stannol.Facile dehydration prevents the isolation of neophyl3SnOH from solution at room temperature and the equilibrium constant for H2O + (neophyl3Sn)2O 2neophyl3SnOH is 0.3 at 304 K.These observations are in sharp contrast with a previous report that the sterically bulky neophyl ligands render neophyl3SnOH stable toward dehydration. 1J(119Sn,13C) observed for neophyl3SnOH and (neophyl3Sn)2CO3 indicates that these compounds, unlike their n-alkyl-substituted homologues, are unassociated in solution, a result attributed to the steric bulk of the neophyl ligand.
