(4-Hydroxy-butoxy)-acetic Acid Methyl Ester, also known as 4-hydroxybutyl acetate or methyl 4-hydroxybutyl acetate, is a chemical compound with the molecular formula C7H14O4. It is a colorless liquid with a fruity, ester-like odor. This ester is formed by the reaction of 4-hydroxybutan-1-ol (also known as 4-hydroxybutyl alcohol) with acetic acid in the presence of a catalyst, resulting in the formation of an ester bond. It is widely used in the flavor and fragrance industry, particularly in the production of artificial fruit flavors, such as apple, pear, and peach, due to its ability to mimic the natural aroma of these fruits. Additionally, it is employed as a solvent and a chemical intermediate in the synthesis of various pharmaceuticals and other organic compounds.
The CAS Registry Mumber 44994-05-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,4,9,9 and 4 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 44994-05: (7*4)+(6*4)+(5*9)+(4*9)+(3*4)+(2*0)+(1*5)=150 150 % 10 = 0 So 44994-05-0 is a valid CAS Registry Number.
