2,5-Difluor-1,4-diaethyl-benzol, also known as 2,5-difluoro-1,4-diethylbenzene, is an organic compound with the chemical formula C10H12F2. It is a derivative of benzene, featuring two fluorine atoms at the 2nd and 5th positions and two ethyl groups at the 1st and 4th positions. This colorless liquid is characterized by its unique electronic properties due to the presence of fluorine atoms, which can influence its reactivity and stability. The compound is primarily used in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals, where its fluorinated structure can impart specific biological activities or improve physical properties. It is also of interest in materials science for the development of new polymers and materials with tailored properties.
The CAS Registry Mumber 704-85-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,0 and 4 respectively; the second part has 2 digits, 8 and 5 respectively. Calculate Digit Verification of CAS Registry Number 704-85: (5*7)+(4*0)+(3*4)+(2*8)+(1*5)=68 68 % 10 = 8 So 704-85-8 is a valid CAS Registry Number.
