4-Pentachlorethyl-benzoylchlorid, also known as 4-(1,2,2,2-tetrachloroethyl)benzoyl chloride, is a chemical compound with the molecular formula C9H4Cl6O. It is a derivative of benzoyl chloride, featuring a pentachlorinated ethyl group attached to the 4-position of the benzene ring. 4-Pentachlorethyl-benzoylchlorid is characterized by its high reactivity due to the presence of the acyl chloride functional group, which can readily undergo nucleophilic substitution reactions. It is used as an intermediate in the synthesis of various organic compounds, particularly those requiring a chlorinated aromatic moiety. Due to its reactivity and potential health and environmental hazards, it is important to handle 4-pentachlorethyl-benzoylchlorid with appropriate safety measures, including the use of personal protective equipment and proper disposal methods.
The CAS Registry Mumber 834-64-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 4 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 834-64: (5*8)+(4*3)+(3*4)+(2*6)+(1*4)=80 80 % 10 = 0 So 834-64-0 is a valid CAS Registry Number.
