Purification Methods

Crystallise the acid from boiling H2O (25mL/g; 63mL/g at 20o), aqueous AcOH (m 180o) Dry it at 100o. The S-benzylisothiuronium salt has m 155-156o (from EtOH). [Price Org Synth 22 611942, Grummitt et al. Org Synth Coll Vol III 449 1955, Beilstein 9 H 857, 9 II 617, 9 III 4266, 9 IV 3343.] The anhydride [703-59-3] M 162.1 has m 141-142o.
