3,4-diphenylselenophene-2-carboxylic acid is an organic compound characterized by a selenophene ring, which is a five-membered aromatic ring containing a selenium atom. This specific compound features two phenyl groups attached to the 3rd and 4th positions of the selenophene ring, and a carboxylic acid functional group at the 2nd position. The carboxylic acid group (-COOH) imparts acidic properties to the molecule, making it capable of donating a proton (H+) in aqueous solutions. The presence of phenyl groups enhances the compound's stability and contributes to its lipophilic nature, which can affect its solubility and potential applications in various chemical and pharmaceutical contexts. 3,4-diphenylselenophene-2-carboxylic acid is of interest in organic synthesis and may have applications in the development of materials with specific electronic or optical properties, as well as in the synthesis of pharmaceuticals.
The CAS Registry Mumber 5408-39-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,0 and 8 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 5408-39: (6*5)+(5*4)+(4*0)+(3*8)+(2*3)+(1*9)=89 89 % 10 = 9 So 5408-39-9 is a valid CAS Registry Number.
