Use
Purify the acid by adsorbing on to a strongly acidic ion-exchange resin (Merck), elute the diacid with aqueous M NaOH, the eluate is evaporated, H2O is added, and filtered through a weakly acidic ion-exchange resin (Merck). The filtrate is then evaporated and recrystallised from EtOH. Its solubility is 0.1g in 1mL of 0.5N HCl. (±)--Kainic acid is recrystallised from H2O with m 230-260o. UV (MeOH): 219 (log 3.9); max 1HNMR (CCl4, 100MHz, Me4Si standard) : 1.64 (s 1H), 1.70 (s 3H), 3.24 (d J 7.5, 2H), 3.3-4.2 (1H), 3.70 (s 3H), 3.83 (s 3H), 4.35 (dd J 7.5, J 14.5, 1H), 5.21 (t J 7.5, 1H), 7.26 (t J 7.5, 1H).
