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 Iodine monobromide has been replaced by 1,3-dibromo-5,5-dimethylhydantoin (DBH) and potassium iodide (KI)

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

PH. EUR. 2002 identifies biotin, flucytosine, polysorbate 80 and sorbic acid using the decolorization of bromine water. These tests can be better performed with 1,3-dibromo-5,5-dimethylhydantoin (DBH) in combination of the reaction with fluorescein sodium resp. sodium bromide. Also fluorescein sodium

Exchange of acyclic glycosyl dithioacetals to their O,O-acetals has been achieved by a generalized reaction protocol mediated by 1,3-dibromo-5,5-dimethylhydantoin under mild, metal-free and neutral conditions. This methodology has been extended to the synthesis of alkyl glycofuranosides.

Die Pharmazie, 59(8), 615-617 (2004-09-24)
The determination of the cationic active disinfectants benzalkonium chloride, benzethonium chloride, cetrimide, and cetylpyridinium chloride according to PH. EUR. 2002 resp. supplement 4.3/2003 can be improved using the DBH-method. By application of column extraction the iodide determination can be performed
