2,7-Dichlor-3-nitro-fluorenon, also known as 2,7-dichloro-3-nitrofluorene, is a chemical compound with the molecular formula C13H6Cl2NO2. It is a yellow crystalline solid that is derived from fluorene, a polycyclic aromatic hydrocarbon. 2,7-Dichlor-3-nitro-fluorenon is characterized by the presence of two chlorine atoms at the 2nd and 7th positions and a nitro group at the 3rd position on the fluorene ring. It is primarily used as an intermediate in the synthesis of various dyes and pigments, particularly those with yellow or orange hues. Due to its chemical structure, 2,7-dichloro-3-nitrofluorene exhibits certain properties such as low solubility in water and high solubility in organic solvents. It is also known for its stability and resistance to degradation, which makes it suitable for industrial applications. However, like many other chemicals, it should be handled with care due to potential health and environmental concerns.
The CAS Registry Mumber 892-54-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,9 and 2 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 892-54: (5*8)+(4*9)+(3*2)+(2*5)+(1*4)=96 96 % 10 = 6 So 892-54-6 is a valid CAS Registry Number.
