Unknown white tablets and aqueous solution were found out togethr with a skeletal corpse. Therefore, these specimens were first applied to the tests of Beilstein-Copper reaction and uranin color reaction on thin-layer. The tablets were positive to both tests but solution was negative.

As the result, the tablets were identifid as bromisovarelylurea,
