Benzenemethanesulfonic acid, 2-hydroxy-, also known as 2-hydroxybenzenemethanesulfonic acid or more commonly as mandelic acid, is an organic compound with the chemical formula C8H8O4S. It is a chiral molecule, meaning it has two enantiomers: (R)-mandelic acid and (S)-mandelic acid. Benzenemethanesulfonic acid, 2-hydroxy- is a derivative of benzene, featuring a hydroxyl group (-OH) at the 2-position and a methanesulfonic acid group (-CH2SO3H) at the 1-position. Mandelic acid is a naturally occurring substance found in small amounts in plants and fruits, such as almonds and bitter almonds. It is also synthesized industrially and has various applications, including as a precursor in the production of pharmaceuticals, as a chiral auxiliary in asymmetric synthesis, and as a flavoring agent in the food industry.
The CAS Registry Mumber 79427-87-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,4,2 and 7 respectively; the second part has 2 digits, 8 and 7 respectively. Calculate Digit Verification of CAS Registry Number 79427-87: (7*7)+(6*9)+(5*4)+(4*2)+(3*7)+(2*8)+(1*7)=175 175 % 10 = 5 So 79427-87-5 is a valid CAS Registry Number.
