Tissue distribution, excretion and metabolism of o-anisidine in rats.

Objectives: The principal commercial use of o-anisidine is believed to be as an intermediate in the manufacture of dyes. It has also been reported to be an intermediate in the manufacture of synthetic guaiacol and its derivatives. o-Anisidine is an urinary bladder carcinogen in mice and rats.

Comparison of tissue distribution and metabolism of 1,2- and 1,4-dibromobenzenes in female rats.

The distribution, excretion and metabolism of 1,4-dibromobenzene (1,4-DBB) and 1,2-dibromobenzene (1,2-DBB), following a single intraperitoneal administration to female Wistar rats, were investigated using radiotracer 3H and GC-MS technique. The maximum level of 3H after 1,4-DBB administration was detected in all examined rat tissues between 4 and 24 h foltowing the injection. The highest concentrations of 3H were found in fat tissue, muscles, adrenal glands and sciatic nerve.

Disposition and metabolism of 1,6-dimethylnaphthalene in rats.

The distribution, excretion and metabolism of 1,6-dimethylnaphthalene following i.p. administration of a single dose of 20 mg/kg to rats, was investigated using radiotracer [3H] and a gas chromatography-mass spectrometry technique (GC-MS).
