1,2-Diphenyl-cyclohexane is an organic compound with the molecular formula C18H18. It is a cyclic hydrocarbon consisting of a cyclohexane ring with two phenyl groups attached to the 1 and 2 positions. 1,2-diphenyl-cyclohexane is known for its unique structure, which results in two distinct chair conformations: the "cis" and "trans" forms. The cis form has an axial-axial interaction, making it less stable, while the trans form has an equatorial-axial interaction, making it more stable. 1,2-Diphenyl-cyclohexane is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its versatile chemical properties and reactivity. It is also used as a chiral auxiliary in asymmetric synthesis and as a ligand in coordination chemistry. The compound is typically synthesized through the Friedel-Crafts alkylation of benzene with cyclohexene in the presence of a Lewis acid catalyst.
The CAS Registry Mumber 84-14-0 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 4 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 84-14: (4*8)+(3*4)+(2*1)+(1*4)=50 50 % 10 = 0 So 84-14-0 is a valid CAS Registry Number.
