Die Pharmazie, 57(1), 45-48 (2002-02-12)
PH. EUR. 2002 uses elemental bromine performing iron limit tests for maleic acid (iron 5 ppm) and titanium dioxide (iron 200 ppm). 1,3-Dibromo-5,5-dimethylhydantoin (DBH) can replace bromine water. For the iron limit test of maleic acid bivalent iron is oxidized

Die Pharmazie, 57(4), 250-251 (2002-05-10)
PH. EUR. 2002 identifies nicotinamid, nicotinic acid, and nikethamide according the reaction of König using cyanogen bromide solution prepared with bromine water and ammonium thiocyanate immediately before use. This colour reaction can be better performed with 1,3-dibromo-5,5-dimethylhydantoin (DBH) and sulphanilic

Die Pharmazie, 57(6), 393-395 (2002-07-16)
Elemental bromine serves as oxidant for the identification of propylthiouracil, 2-thiouracil and sulphur according to PH. EUR. 2002. Phenol is identified according to PH. EUR. 2002 with bromine water as the sparingly water-soluble 2,4,4,6-tetrabromo-2,5-cyclohexadiene-1-one. These tests can be performed better

Die Pharmazie, 59(8), 612-614 (2004-09-24)
Iodine values (iodine numbers) of several fixed oils and lard can be determined in ethyl acetate, an easily biodegredable solvent, instead of chloroform according to PH. EUR. 2002. Iodine monobromide has been replaced by 1,3-dibromo-5,5-dimethylhydantoin (DBH) and potassium iodide (KI)
