Did you run a marquis and mecke test on it? What did the bits look like that didn't dissolve? I've had pretty pure 2CE dissolve in water easily but leave a small bit of yellowish waxy material undissolved (1mg out of 20mg perhaps).
There really is no way for us to ID what you have but you can do the color tests and maybe get a closer idea for yourself.
