Fellow Fluorinators:

My understanding from a couple of years ago is that Ozark-Mahoning decided
to discontinue production of BrF5, but still had some on hand.  At that time
they had difficulty producing or shipping sufficiently pure product.
Perhaps Dave's experience is a dawn of hope.

But.... if you are considering ordering BrF5 from China, contact me first.
