Human Endogenous Metabolite | [Purification Methods]
Purify D-(+)-ribonic acid--lactone by recrystallisation from EtOAc. The tribenzoate has m 54-56o (from AcOH), [] D 25 +27o (c 2.37, Me2NCHO), and the 3,5-O-benzylidene derivative has m 230-231.5o (needles from Me2CO-pet ether) and [] D 25 -177o (CHCl3).
