It is a white crystalline solid that is insoluble in water but soluble in organic solvents. bis-(3-chloro-phenyl)-sulfone is primarily used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. It is also employed in the production of dyes and pigments. Bis-(3-chloro-phenyl)-sulfone is synthesized through the reaction of 3-chlorophenol with sulfuric acid, followed by oxidation. Due to its reactivity and the presence of chlorine atoms, it is essential to handle bis-(3-chloro-phenyl)-sulfone with care, as it may pose health and environmental risks.
The CAS Registry Mumber 5097-16-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,9 and 7 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 5097-16: (6*5)+(5*0)+(4*9)+(3*7)+(2*1)+(1*6)=95 95 % 10 = 5 So 5097-16-5 is a valid CAS Registry Number.
