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!
