I surprised that it did not

I surprised that it did not dissolve in DMSO, given that it is essentially a lipophilic thiamine.
I did find a report that crystallized it out of an ethanol solution - seems like Sigma also provides it in an Ethanol solution (or atleast it used to)
(Acta Cryst. (1993). C49, 294-298 [ doi:10.1107/S0108270192006905 ]
Structure of benfotiamine hemihydrate).

Hi,

Hi,

I tried to get in touch with the scientists from the papers you suggested but in vain :(
I am totally clueless about Benfotiamine now !

Check out the first ref -

Check out the first ref - they describe the EtOH/H2O solution, and contact Sigma to see if they can provide you with what that group used.
