1262-78-8 Usage
Uses
Used in Plastics Industry:
TMPST is used as a stabilizer in the production of polyvinyl chloride (PVC) plastics. It is added to PVC to prevent degradation caused by heat, light, and oxygen exposure, thereby enhancing the durability and longevity of the material.
Used in Chemical Synthesis:
TMPST is utilized as a catalyst in organic synthesis reactions, particularly in the formation of carbon-carbon and carbon-heteroatom bonds. Its effectiveness in these reactions contributes to the advancement of chemical processes and the production of various compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 1262-78-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,6 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1262-78:
(6*1)+(5*2)+(4*6)+(3*2)+(2*7)+(1*8)=68
68 % 10 = 8
So 1262-78-8 is a valid CAS Registry Number.

Tetraneophyltin and its derivatives: The effects of steric hindrance in organotin chemistry
Reichle, Walter T.
, p. 87 - 91 (2008/10/08)
Tetraneophyltin has been prepared and its chemical reactions and derivatives subjected to study. The very severe steric crowding inhibits tin-carbon bond cleavage reactions in the tetraneophyltin or chloride displacement reactions in trineophyltin chloride. By various techniques the following compounds were prepared : [C6H5C(CH3)2CH2] 3SnX: X = F, Cl, Br, I, OH, S1/2, N3, NO3, ClO4, O2CCH3, O2CCF3, O2CH. The fluoride is a low-melting, hydrocarbon-soluble derivative; the acetate, formate, and perfluoroacetate have normal ester carbonyl absorptions (1650-1700 cm.-1). The nitrate and perchlorate are both bidentate ligands attached to five-coordinate tin atoms; all other derivatives have four-coordinate tin atoms. Neither the hydrosulfide nor the oxide (X = SH, O1/2) could be prepared. The infrared, nuclear magnetic resonance, and M?ssbauer spectra of these compounds have been correlated.
