Of all the bogus crap I have to put up with in the lab. I grew more "crystals" from the same solution that didn't diffract well enough. Instead of taking them right over to the crystallographer, I had enough to take and NMR and then, if pure, enough to send off for elemental analysis. So I took the NMR. Starting material. Effing A, D.
Nothing is more frustrating than spending large amounts of time and effort on purifying starting materials that were apparently only dirtied with extraneous reagent.
