General Description
P-Toluene-sulfonic acid N-octadecyl ester, also known as octadecyl p-toluenesulfonate, is a long-chain alkyl ester of p-toluene-sulfonic acid. It is a white to off-white solid that is soluble in organic solvents and often used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and surfactants. This chemical is commonly employed as an ion-pairing reagent for the HPLC analysis of polar compounds and as a phase transfer catalyst for organic reactions. It is also used as an emulsifier and wetting agent in various industrial processes and formulations. Additionally, it can act as a corrosion inhibitor and detergent in metalworking fluids and cleaning products. Overall, p-toluenesulfonic acid N-octadecyl ester has a wide range of applications in the chemical industry due to its surfactant and solubility properties.
Check Digit Verification of cas no
The CAS Registry Mumber 3386-32-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,8 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3386-32:
(6*3)+(5*3)+(4*8)+(3*6)+(2*3)+(1*2)=91
91 % 10 = 1
So 3386-32-1 is a valid CAS Registry Number.

Solvent-free and selective tosylation of alcohols and phenols with p-toluenesulfonyl chloride by heteropolyacids as highly efficient catalysts

Tosylation of some alcohols and phenols has been directly carried out with p-toluenesulfonyl chloride using heterodoxy acids (H3PW 12O40, H3PMo12O40, A 3PW12O40, and AlPMo12O40) as catalysts in the absence of solvent. We found that heteropoly acids AlPW12O40 and AlPMo 12O40 were effective catalysts for the tosylation of alcohols and phenols. In the case of aliphatic alcohols, secondary alcohols undergo tosylation chemoselectively in the presence of primary hydroxyl groups. This new method consistently has the advantage of excellent yields and short reaction time.
