4-Ethylfluorene is an organic compound with the chemical formula C15H14. It is a derivative of fluorene, a polycyclic aromatic hydrocarbon, with an ethyl group attached to the 4-position of the fluorene ring. 4-ethylfluorene is characterized by its unique structure, which consists of three fused benzene rings and a six-membered ring, with the ethyl group extending from one of the carbon atoms. 4-Ethylfluorene is a colorless to pale yellow solid with a melting point of approximately 54-56°C. It is insoluble in water but soluble in organic solvents such as ethanol and acetone. Due to its aromatic nature, 4-ethylfluorene exhibits various chemical properties, including electrophilic substitution reactions and the ability to form complexes with metal ions. It is primarily used as an intermediate in the synthesis of various organic compounds and dyes, as well as in the production of advanced materials like polymers and pharmaceuticals.

1687-91-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1687-91-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,8 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.Calculate Digit Verification of CAS Registry Number 1687-91:
(6*1)+(5*6)+(4*8)+(3*7)+(2*9)+(1*1)=108
108 % 10 = 8
So 1687-91-8 is a valid CAS Registry Number.
