Uses
Used in Organic Synthesis:
2,3,4,6-tetramethylpyridine is used as a catalyst for various organic synthesis reactions, particularly in the production of pharmaceuticals and agrochemicals. It aids in the formation of desired compounds by lowering the activation energy of the reaction, thereby increasing the reaction rate and efficiency.
Used in Paints and Coatings Industry:
2,3,4,6-tetramethylpyridine is used as a solvent in the manufacturing of paints and coatings. It helps in dissolving the pigments and resins, ensuring a smooth and even application of the paint or coating.
Used in Corrosion Inhibition:
2,3,4,6-tetramethylpyridine functions as a corrosion inhibitor, protecting metal surfaces from oxidation and corrosion. It forms a protective film on the metal surface, preventing the contact of corrosive agents and reducing the rate of corrosion.
Used in Industrial Processes:
2,3,4,6-tetramethylpyridine is used as a stabilizer in some industrial processes. It helps in maintaining the stability of the process by preventing unwanted side reactions and ensuring the desired outcome.
However, it is important to note that 2,3,4,6-tetramethylpyridine is considered to be hazardous to human health and the environment, and should be handled with care to minimize potential risks.
Check Digit Verification of cas no
The CAS Registry Mumber 20820-82-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,2 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20820-82:
(7*2)+(6*0)+(5*8)+(4*2)+(3*0)+(2*8)+(1*2)=80
80 % 10 = 0
So 20820-82-0 is a valid CAS Registry Number.

ACYLATION D'ALCENES DANS LE SYSTEME ACYLANT ACIDE TRIFLUOROMETHANESULFONIQUE-HALOGENURE D'ACIDE
Roussel, Christian,Rajoharison, Harivelo G.,Metzger, Jacques
, p. 613 - 618 (2007/10/03)
The diacylation of 2-methyl-2-pentene and of related alcoholic precursors with trifluoromethanesulphonic acid/acetyl chloride was investigated. The initially formed pyrylium salts were converted directly into the corresponding pyridines. The influence of the reaction conditions (temperature; molar ratios AcCl/F3CSO3H/alkene; experimental procedure) was thoroughly examined permitting the observation of new aspects for the examined synthesis of pyrylium salts e.g.: a) formation of less substituted pyrylium salts 2 up to 94 percent selectivity; b) direct access to isomeric pyrylium salts 1 and 2 depending on the reaction conditions; c) formation of triacylation products 3, 4 which could be suppressed in favour of 2. The described procedure presents also experimental advantages (no crackings; easily tractable reaction mixtures).
