The thallium was slipped into bottles of Coca-Cola at the Carr and Trepal homes. [27] Thallium was the poison of choice for Saddam Hussein to use on dissidents, which even allowed for them to emigrate before dying. [28] In 1995, Zhu Ling was the victim of an unsolved attempted thallium poisoning in Beijing, China.
Thallium(III) acetate is the acetate salt of thallium, with the chemical formula Tl(CH 3 COO) 3. As a selective culture medium in microbiology, [1] thallium acetate is toxic, [2] but it can also be used as a hair loss agent. Koremlu, a depilatory that contained the rat poison Thallium acetate was widely marketed during th 1930s.
The radioisotope thallium-201 (as the soluble chloride TlCl) is used in small amounts as an agent in a nuclear medicine scan, during one type of nuclear cardiac stress test. Soluble thallium salts (many of which are nearly tasteless) are highly toxic and they were historically used in rat poisons and insecticides .
Similarly, thallium(I) aryl compounds require steric bulk for their isolation. [4] A well-known organothallium(I) species is thallium cyclopentadienide. It arises by treatment of thallium(I) salts, such as thallium sulfate, with cyclopentadiene. Thallium(I) cyclopentadienide adopts a zig-zag chain structure of cyclopentadienide and thallium. [5]
Thallous acetate or thallium(I) acetate is a salt of thallium and acetate with the chemical formula TlCH 3 COO. It is used in microbiology as a selective growth ...
Thallium(I) nitrate, also known as thallous nitrate, is a thallium compound with the formula Tl NO 3. It is a colorless and highly toxic salt. It is a colorless and highly toxic salt. Preparation
Gallium scan showing panda (A) and lambda (B) patterns, considered specific for sarcoidosis in the absence of histological confirmation. In the past, the gallium scan was the gold standard for lymphoma staging, until it was replaced by positron emission tomography (PET) using 18 F-fluorodeoxyglucose (FDG).
Thallium (81 Tl) has 41 isotopes with atomic masses that range from 176 to 216. 203 Tl and 205 Tl are the only stable isotopes and 204 Tl is the most stable radioisotope with a half-life of 3.78 years. 207 Tl, with a half-life of 4.77 minutes, has the longest half-life of naturally occurring Tl radioisotopes.
