If you were unable to locate any information with a simple web search or two - then something is amiss.


From what I can tell, this is not a commercially available material - and it is only mentioned in a couple of patent applications. 


In a document that appears to be translated from Thai to Chinese to English by an individual who speaks Spanish:


http://www.google.tl/patents/CN103649057B?cl=en&hl=pt-PT

Paragraph 0797, mentions a compound 

1- [4- (4_ chlorophenoxy) -2-trifluoromethyl-phenyl] ethanone

This is likely a bad translation of 

Ethanone 1-[4-(4-chlorophenoxy)-2(trifluoromethyl)phenyl]-

Here, the material is described briefly as an intermediate, not as a product.

The compound is further detailed at 
https://www.surechembl.org/chemical/SCHEMBL15756967
under the name of 

1-[4-(4-chlorophenoxy)-2-methylphenyl]ethan-1-one

but no mention of any CAS number on anything I located.


My best guess would be to not trust the label on the container, treat the materials as an unknown, and send a sample off to a waste company for characterization and a disposal proposal.

All,

 

I am stymied here.  I have a customer who presented a vessel that previously contained a material with the CAS number 1417782-28-5 for cleaning.  The chemical name on the SDS is "Ethanone, 1-[4-(4-chlorophenoxy)-2(trifluoromethyl)phenyl]-".  I tried to look it up on the CAS site and got "No Results".  I called the manufacturer and they couldn't find the product either by CAS number or product number.  They said they would get back to me.  Any suggestions would be greatly appreciated.  I just want to know if I can safely wash this vessel without harming my employees, the environment, or the downstream POTW.  Thanks!

 

Mark Ellison
