Off-white powder

Purification Methods

Purify it by repeated precipitation from alkaline solution with acid (preferably AcOH or formic acid), filter, wash well with H2O, then EtOH and dry at 100o. The purity is checked by paper chromatography [RF 0.15 (n-BuOH/AcOH/H2O, 4:1:1); 0.33 (3% aqueous NH4OH). [Goto et al. Arch Biochem Biophys 111 8 1965.] [For biochemistry see Blakley Biochemistry of Folic Acid and Related Pteridines North Holland Publ Co, Amsterdam 1969.] [Beilstein 26 III/IV 3999.]
