Aldehyde purification

Hi, Clarke!

Your old trick, the aldehyde bisulfite adduct, worked beautifully for us recently, reproducibly yielding a nice crystalline material and boosting purity from 85% to 99%. We regenerated the aldehyde through treatment with TMSCl in acetonitrile. I owe you one!

Need help

Hello Kilomentor,

I am trying to get crystal of bicarbocyclic ketone substrate for single X-ray analysis. I am unable to get a proper crystal for the corresponding oxime derivative. Please suggest me any derivatives with good crystallinity.

Your help very much appreciated.
