Properties: Snow-white crystals from chloroform. Freely sol in water, acetone. Less sol in ether, chloroform. Practically insol in petr ether. Aq solns should be adjusted to a pH of about 5 and can be stored at room temp or lower. Such solns have been stored at 45° for 5 days without deterioration. The soly in polar solvents increases as the temp decreases.
Use: As reagent for determination of potassium, ammonium, rubidium and cesium ions: Barnard, Buechl, Chemist-Analyst 48, 44, 49 (1959); Montequi, Serrano, An. R. Acad. Farm. 26, 107 (1960).
