Stannane, tributyl(1,1-dimethylethoxy)-, also known as tributyl(1,1-dimethylethoxy)stannane, is an organotin compound with the chemical formula C12H29OSn. It is a colorless liquid at room temperature and is soluble in organic solvents. Stannane, tributyl(1,1-dimethylethoxy)- is primarily used as a catalyst in various chemical reactions, particularly in the production of polyurethane foams and as a stabilizer for PVC. It is also employed in the synthesis of other organotin compounds. Due to its potential environmental and health risks, including toxicity and bioaccumulation, the use of this chemical is subject to strict regulations in many countries.

Check Digit Verification of cas no

The CAS Registry Mumber 2724-79-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,2 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2724-79:
(6*2)+(5*7)+(4*2)+(3*4)+(2*7)+(1*9)=90
90 % 10 = 0
So 2724-79-0 is a valid CAS Registry Number.

Reactivity of carbon dioxide with n-butyl(phenoxy)-,(alkoxy)-, and (oxo)stannanes: insight into dimethyl carbonate synthesis

Ballivet-Tkatchenko,Douteau,Stutzmann

, p. 4563 - 4567 (2008/10/08)

The CO2 insertion into Sn-O bonds of a series of butyl(phenoxy)-, (alkoxy)-, and (oxo)-stannanes has been investigated. The tributyl derivatives Bu3SnOR (2a, R = Me; 3a, R = iPr; 4a, R = tBu; 5a, R = SnBu3)1 give quantitatively Bu3Sn(OCO2R), 2b-5b; the analogous tributylphenoxystannane, 1, is less reactive. For the dibutyl series, Bu2Sn(OR)2, steric effects of tBu groups in OR (8a) suppress carbonation under atmospheric pressure. With R = Me (6a) or R = iPr (7a), only one Sn-OR bond reacts, resulting in Bu2Sn(OR)(OCO2R), 6b or 7b. Treating 6a with 2-propanol affords under CO2 the mixed compound Bu2Sn(OMe)-(OCO2iPr), selectively. Facile deinsertion of CO2 is a common property of all compounds, occurring more readily in the dibutyl series. The stoichiometric transformation of the carbonato ligand in 2b, 5b, or 6b to dimethyl carbonate (DMC) on reaction with MeI requires nucleophilic assistance by F- to proceed. In the presence of MeOH, 2b and 5b are almost inactive for DMC formation, in contrast with 6b. The best yield is obtained under supercritical CO2-methanol conditions.
