4-(4-Jod-benzoyloxy)-buttersaeure-methylester, also known as methyl 4-(4-iodobenzoyloxy)butyrate, is a chemical compound with the molecular formula C12H15IO4. It is a derivative of butyric acid, featuring a methyl ester group, a benzoyloxy group, and an iodine atom attached to the benzene ring. <4-(4-Jod-benzoyloxy)-buttersaeure>-methylester is primarily used as an intermediate in the synthesis of various pharmaceuticals and organic compounds due to its unique structure and reactivity. Its properties include a melting point of 54-56°C and a density of 1.6 g/cm3. Methyl 4-(4-iodobenzoyloxy)butyrate is typically synthesized through the reaction of butyric acid with 4-iodobenzoyl chloride in the presence of a base, such as sodium hydroxide. The compound is sensitive to light and moisture, so it should be stored in a cool, dry place and protected from light.
The CAS Registry Mumber 3540-62-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,4 and 0 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 3540-62: (6*3)+(5*5)+(4*4)+(3*0)+(2*6)+(1*2)=73 73 % 10 = 3 So 3540-62-3 is a valid CAS Registry Number.
