GHS Hazard Classification

Documented Uses

• Strong mutagen found in broiled foods. [ChemIDplus] Naturally produced when meats are heated or cooked; Used as a research chemical; [HSDB]
• No known commercial use.[DHHS/National Toxicology Program; Eleventh Report on Carcinogens: 2-Amino-3,8-Diemethylimidazo
• MeIQx was prepared in 21% overall yield from 4-fluoro-o-phenylenediamine. The 3,7-dimethyl isomer may be obtained as a minor by-product. The [14]C-label was introduced in the last step through cyclization with [14]C-cyanogen bromide. An alternative synthesis of MeIQx from p-fluoroaniline avoided the separation of isomers but gave poorer yield.
• ... heterocyclic amine formed during heating or cooking and /is/ found in cooked meat and fish
• Substances that increase the risk of NEOPLASMS in humans or animals. Both genotoxic chemicals, which affect DNA directly, and nongenotoxic chemicals, which induce neoplasms by other mechanism, are included.
• Chemical agents that increase the rate of genetic mutation by interfering with the function of nucleic acids. A clastogen is a specific mutagen that causes breaks in chromosomes.
