5847-52-9 Usage
Description
Tributyltin chloroacetate is a chemical compound consisting of tributyltin and chloroacetic acid. It is known for its use as a catalyst in esterification and transesterification reactions, as well as in the synthesis of PVC stabilizers. However, it is highly toxic to aquatic organisms and has been banned in many countries due to its harmful effects on marine life and potential for bioaccumulation in the food chain. Additionally, it has endocrine-disrupting properties, causing adverse reproductive and developmental effects in mammals. Due to its toxic nature, strict regulations and restrictions have been imposed on the use and handling of tributyltin chloroacetate to minimize its environmental and health risks.
Uses
Used in Chemical Industry:
Tributyltin chloroacetate is used as a catalyst for esterification and transesterification reactions, which are important processes in the synthesis of various chemicals and compounds.
Used in Plastics Industry:
It is also used in the synthesis of PVC stabilizers, which are essential for preventing the degradation of PVC materials and maintaining their durability and performance.
However, due to its highly toxic nature and potential for bioaccumulation in the food chain, the use of tributyltin chloroacetate has been restricted or banned in many countries. Alternative catalysts and stabilizers have been developed to replace tributyltin chloroacetate in various applications to minimize its environmental and health risks.
Check Digit Verification of cas no
The CAS Registry Mumber 5847-52-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,4 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5847-52:
(6*5)+(5*8)+(4*4)+(3*7)+(2*5)+(1*2)=119
119 % 10 = 9
So 5847-52-9 is a valid CAS Registry Number.

The β-effect with vinyl cations: Kinetic study of the protiodemetalation of silyl-, germyl-, and stannylalkynes
Dallaire, Carol,Brook, Michael A.
, p. 2332 - 2338 (2008/10/08)
The relative magnitude of the hyperconjugative stabilization of vinyl cations by adjacent C-M bonds (M = Si, Ge, Sn; the β-effect) has been examined by measuring the rate constants for the protonation and subsequent protiodemetalation of group 14 metalated (trimethylsilyl)-acetylenes (R3MC≡CSiMe3). The relative β-effect arising from the second-order rate constants Sn ? Ge > Si (maximum kM/kSi = 108, 5 × 102, 1, respectively) follows the same order as that reported for simple carbenium ions. The product ratio from the protonation of Ph3GeC≡CSiMe3 was found to be particularly sensitive to acid concentration and strength, leading to loss of Ph3Ge preferentially with weaker acids. With tin groups, the rate of destannylation decreased with increasing steric bulk, unlike the corresponding situation with silyl groups. The origins of both these observations may be attributed to nucleophilic interaction at the metal center during protonation.
