Octanophenone can be analyzed by this reverse phase (RP) HPLC method with simple conditions. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 μm particles columns available for fast UPLC applications. This method is scalable and can be used for isolation impurities in preparative separation.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day.
