Description
Tetrabutylammonium 4-toluenesulfonate, also known as TBAOTs, is a quaternary ammonium salt that serves as a versatile reagent in various chemical reactions and processes. It is characterized by its ability to facilitate phase transfer and improve the solubility of organic compounds in aqueous solutions.
Uses
Used in Organic Synthesis:
Tetrabutylammonium 4-toluenesulfonate is used as a phase transfer catalyst (PTC) for SN2 fluorinations, enabling the efficient and selective introduction of fluorine atoms into organic molecules. This application is particularly valuable in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals.
Used in Conducting Polymers:
In the field of materials science, TBAOTs is used as an electrolyte in the preparation of conducting polymer polypyrrole (PPy) through electrochemical polymerization techniques. This process allows for the formation of PPy with enhanced electrical conductivity and stability, making it suitable for applications in sensors, batteries, and other electronic devices.
Used in Reagent Synthesis:
Tetrabutylammonium 4-toluenesulfonate is also employed as a reagent to synthesize 1-alkynyl sulfonates from 1-alkynyl-bromanes via Michael-carbene rearrangement reactions. This method provides a convenient and efficient route to access a variety of alkynyl sulfonate compounds, which are valuable intermediates in organic synthesis and can be further transformed into a range of functionalized molecules.
Check Digit Verification of cas no
The CAS Registry Mumber 7182-86-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,8 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7182-86:
(6*7)+(5*1)+(4*8)+(3*2)+(2*8)+(1*6)=107
107 % 10 = 7
So 7182-86-7 is a valid CAS Registry Number.
