1,1,1-trichloro-2,2-bis-(4-fluoro-3,5-dinitro-phenyl)-ethane, also known as TCDF, is a highly toxic and persistent environmental pollutant. It is a dioxin-like compound, which means it shares similar chemical properties and toxic effects with dioxins. TCDF is formed as a byproduct during the synthesis of certain chlorinated chemicals, such as the herbicide 2,4,5-T. It is characterized by its chlorine and fluorine atoms, as well as its nitro groups, which contribute to its stability and resistance to degradation. Due to its toxicity, TCDF has been linked to various health issues, including cancer, reproductive and developmental problems, and immune system dysfunction. As a result, it is subject to strict regulations and monitoring in the environment and industrial processes.
The CAS Registry Mumber 446-69-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,4 and 6 respectively; the second part has 2 digits, 6 and 9 respectively. Calculate Digit Verification of CAS Registry Number 446-69: (5*4)+(4*4)+(3*6)+(2*6)+(1*9)=75 75 % 10 = 5 So 446-69-5 is a valid CAS Registry Number.
