Description
ACETOACETIC ACID ISOAMYL ESTER, also known as Isoamyl acetoacetate, is a synthetic flavoring agent characterized by its ethereal, sweet, winy odor and green-apple flavor. It is a stable, colorless liquid with a light green leaf-fruity odor, and should be stored in glass or tin containers to maintain its quality.
Uses
Used in Food and Beverage Industry:
ACETOACETIC ACID ISOAMYL ESTER is used as a flavoring agent for imparting a green-apple flavor and light green leaf-fruity aroma to various food and beverage products. It is particularly used in currant and berry flavors for applications in beverages, candy, and ice cream at concentrations ranging from 5–15 ppm.
This synthetic flavoring agent is valued for its ability to enhance the taste and aroma of food products, providing a refreshing and fruity note that appeals to consumers. Its stability and compatibility with other ingredients make it a versatile option for use in a wide range of food and beverage applications.
Preparation
By transesterification of ethyl acetylacetate with isoamyl alcohol in the presence of sodium.
Check Digit Verification of cas no
The CAS Registry Mumber 2308-18-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,0 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2308-18:
(6*2)+(5*3)+(4*0)+(3*8)+(2*1)+(1*8)=61
61 % 10 = 1
So 2308-18-1 is a valid CAS Registry Number.
