Thallous acetate or thallium(I) acetate is one of two salts of thallium and acetate; it has chemical formula TlCH3COO. It is used in microbiology as a selective growth medium. It is poisonous.
Unlike higher homologues, which undergo the Hunsdiecker reaction, thallium(I) acetate reacts with bromine to give the thallium(III) salt TlBr2OAc.
