2-acetoxy-1,1-bis-(4-chloro-phenyl)-ethane, also known as bis(4-chlorophenyl) acetate or 4,4'-Dichlorobenzhydrol acetate, is an organic compound with the chemical formula C16H12Cl2O2. It is a white crystalline solid that is used as an intermediate in the synthesis of various chemicals, including pesticides and pharmaceuticals. 2-acetoxy-1,1-bis-(4-chloro-phenyl)-ethane is characterized by its two 4-chlorophenyl groups attached to an ethane molecule, with an acetoxy group at the 2-position. It is known for its relatively low solubility in water and is typically used in the production of dichlorvos, a widely used insecticide. Due to its potential health and environmental risks, handling and disposal of this chemical must be done with proper safety measures and in accordance with local regulations.

3305-00-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3305-00-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,0 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3305-00:
(6*3)+(5*3)+(4*0)+(3*5)+(2*0)+(1*0)=48
48 % 10 = 8
So 3305-00-8 is a valid CAS Registry Number.

Substituent Effect Studies of Aryl-Assisted Solvolyses. I. The Acetolysis of 2,2-Bis(substituted phenyl)ethyl p-Toluenesulfonates

Fujio, Mizue,Maeda, Yasuyuki,Goto, Mutsuo,Saeki, Yoshihiro,Mishima, Masaaki,Tsuno, Yuho

, p. 3015 - 3020 (2007/10/02)

The substituent effect on the acetolysis of 2,2-bis(substituted phenyl)ethyl p-toluenesulfonates at 90.10 deg C can be described accurately in terms of the Yukawa-Tsuno (LArSR) relationship, giving a ρ value of -4.44 and an r value of 0.53. The substituent effect correlation of this system carrying two aryls is quite comparable to that of the 2-methyl-2-phenylpropyl system carrying a single aryl group, suggesting the close similarity in the structure of the transition states between the systems. The results can be reasonably accounted for on the basis of the accepted mechanism of this reaction, involving a rate-determining aryl-assisted transition state where only one aryl group of the two β-aryl groups participates.
