1518-72-5 Usage

General Description

DIISOBUTYL DISULFIDE is a chemical compound with the molecular formula C8H18S2. It is a colorless to pale yellow liquid with a strong odor similar to garlic or onions. DIISOBUTYL DISULFIDE is commonly used as a flavoring agent in the food industry, as well as a fragrance ingredient in perfumes and personal care products. It is also used in the production of rubber, plastics, and other industrial applications. However, exposure to DIISOBUTYL DISULFIDE can cause irritation to the skin, eyes, and respiratory system, and it may have harmful effects on aquatic organisms. Therefore, proper safety precautions should be taken when handling this chemical.

Check Digit Verification of cas no

The CAS Registry Mumber 1518-72-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,1 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1518-72:
(6*1)+(5*5)+(4*1)+(3*8)+(2*7)+(1*2)=75
75 % 10 = 5
So 1518-72-5 is a valid CAS Registry Number.

Method for preparing disulfide bond containing compound by using TEMPO catalyst through aerobic oxidation

-

Paragraph 0065; 0066; 0067; 0068; 0069; 0129-0132, (2016/10/07)

The invention discloses a method for preparing a disulfide bond containing compound by using a TEMPO catalyst through aerobic oxidation. The method comprises the following steps: adding R-SH, R'-SH and TEMPO into a solvent, and performing heating reflux in an aerobic environment, thereby preparing R-S-S-R'. The method achieves oxidative coupling reaction of thiophenol and mercaptan in the absence of transition metal and is high in yield, good in selectivity and free of over-oxidized product; for aliphatic mercaptan which is relatively poor in activity, the problem of oxidation can be solved by adding copper salt as a promoter, the yield is relatively high, and the reaction is greatly affected by a substitute group; the catalyst is easy to obtain, the reaction condition is gentle, and the method is applicable to large-scale production.

Methyl sulfinates as electrophiles in friedel-crafts reactions. Synthesis of aryl sulfoxides

Yuste, Francisco,Hernandez Linares, Angelica,Mastranzo, Virginia M.,Ortiz, Benjamin,Sanchez-Obregon, Ruben,Fraile, Alberto,Garcia Ruano, Jose Luis

scheme or table, p. 4635 - 4644 (2011/07/29)

The Friedel-Crafts reaction of methyl alkyl- and arylsulfinates with aromatic systems, activated by one or more electron-donating substituents (OH, OMe, NHR, NR2), provides alkyl aryl and diaryl sulfoxides under mild conditions and in moderate to good yields. The very high regioselectivity usually observed in these sulfinylation reactions is rationalized on the basis of a Wheland intermediate having a trigonal bypyramidal structure in which steric and electronic interactions are significant factors strongly destabilizing the attack to the ortho positions.
