α,α'-Bis-trichlormethyl-p-xylol and p-Bis-<β,β,β-trichloraethyl>-benzol are two distinct chemical compounds. α,α'-Bis-trichlormethyl-p-xylol, also known as 4,4'-bis(trichloromethyl)-1,2-dimethylbenzene, is a white crystalline solid with the chemical formula C10H10Cl6. It is a derivative of xylol, a common name for dimethylbenzene, with two trichloromethyl groups attached to the para positions. On the other hand, p-Bis-<β,β,β-trichloraethyl>-benzol, or 1,4-bis(2,2,2-trichloroethyl)benzene, is a colorless liquid with the chemical formula C10H10Cl6. It features a benzene ring with two 2,2,2-trichloroethyl groups attached to the para positions. Both compounds are used in various industrial applications, such as chemical intermediates and in the production of flame retardants. Due to their toxic nature and potential health risks, handling these chemicals requires proper safety measures and adherence to regulations.
The CAS Registry Mumber 13454-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,5 and 4 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 13454-21: (7*1)+(6*3)+(5*4)+(4*5)+(3*4)+(2*2)+(1*1)=82 82 % 10 = 2 So 13454-21-2 is a valid CAS Registry Number.
