Cyclopentanecarbonylchloride, 1-phenyl- , with the CAS register number 17380-62-0, has other names such as α-Phenylcyclopentanecarbonyl chloride ; 1-Phenylcyclopentane-1-carbonyl chloride ; 1-Phenylcyclopentanecarboxylic acid chloride , etc. Its chemical formula is C12H13ClO with 12 carbon, 13 hydrogen, 1 oxygen.

This is a kind of liquid with the boiling point of 149-150℃/2.92kPa. As for its usage, it is usually applid in the pharmaceutics intermediate, such as the intermediate for the carbetapentane citrate and
caramiphen ethanedisulfonate .

As for its production method, you could follow the below steps:  Firstly, cyclize with1,4-Dibromobutane and Benzyl cyanide under the alkalinity condition and hydrolyze, then we could get the 1-Phenyl-1-cyclopentanecarbonitrile . Secondly, chloridize 1-Phenyl-1-cyclopentanecarbonitrile and phosphorus trichloride , then we could get what we need.

The preparation products of Cyclopentanecarbonylchloride are as below: caramiphen hydrogen edisilate , Pentoxyverine , and caramiphen . And its raw materials are 1-Phenylcyclopentanecarboxylic acid , 1,4-Dibromobutane , and 1-Phenyl-1-cyclopentanecarbonitrile .
