Undecanoic acid, 3-methyl-, ethyl ester, (R)-, also known as (R)-ethyl 3-methylundecanoate, is a chiral organic compound with the molecular formula C13H26O2. It is an ester derived from 3-methylundecanoic acid and ethanol, featuring a 3-methyl branch on the undecyl chain. Undecanoic acid, 3-methyl-, ethyl ester, (R)- is characterized by its fruity, apple-like odor and is commonly used in the fragrance industry to create natural, fresh, and fruity scents. It can be found in various fruits, such as apples and pears, and is also used as a flavoring agent in food products. Due to its chiral nature, it exists as two enantiomers, with the (R)-enantiomer being the one described here.
The CAS Registry Mumber 84567-93-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,6 and 7 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 84567-93: (7*8)+(6*4)+(5*5)+(4*6)+(3*7)+(2*9)+(1*3)=171 171 % 10 = 1 So 84567-93-1 is a valid CAS Registry Number.
