6640-78-4 Usage
General Description
Benzoic acid, 3-methyl-, (2-methylpropyl) ester is a chemical compound commonly known as isobutyl benzoate. It is a clear, colorless liquid with a fruity, floral odor, and is commonly used as a fragrance ingredient and solvent in the cosmetics and personal care industry. It is also used as a flavoring agent in food, and as a plasticizer in the manufacturing of plastics and resins. Isobutyl benzoate is considered to be a safe and non-toxic compound when used in controlled amounts, but can cause irritation to the skin and eyes in high concentrations. Overall, it is a versatile chemical with a wide range of industrial applications.
Check Digit Verification of cas no
The CAS Registry Mumber 6640-78-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,4 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6640-78:
(6*6)+(5*6)+(4*4)+(3*0)+(2*7)+(1*8)=104
104 % 10 = 4
So 6640-78-4 is a valid CAS Registry Number.

Efficient and selective palladium-catalyzed direct oxidative esterification of benzylic alcohols under aerobic conditions
Hu, Yongke,Li, Bindong
, p. 7301 - 7307 (2017)
A highly efficient palladium-catalyzed approach for the direct oxidative esterification of benzylic alcohols with methanol and long-chain aliphatic alcohols under mild conditions has been achieved. This practical catalyst system exhibits a broad substrate scope and good functional group tolerance. Catalytic amount of Bi(OTf)3 is used as co-catalyst to improve the activity and selectivity of the reactions. A variety of esters are obtained in yields of 43–96%.
