(+/-)-4-(4-Fluor-phenyl)-hex-2-ensaeure, also known as (±)-4-(4-fluorophenyl)-hex-2-enoic acid, is a chiral organic compound with the molecular formula C12H13FO2. It features a hexenoic acid backbone, with a 4-fluorophenyl group attached at the 4th position. (+/-)-4-(4-Fluor-phenyl)-hex-2-ensaeure is characterized by its asymmetric carbon atom, which results in two enantiomeric forms: the R- and S-isomers. The presence of the fluorine atom in the phenyl ring imparts unique electronic and steric properties to the molecule, making it a potentially valuable building block in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. Its applications may include the development of chiral ligands, catalysts, or as an intermediate in the preparation of more complex molecules with specific biological activities.
The CAS Registry Mumber 2721-05-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,2 and 1 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2721-05: (6*2)+(5*7)+(4*2)+(3*1)+(2*0)+(1*5)=63 63 % 10 = 3 So 2721-05-3 is a valid CAS Registry Number.
