一般描述
Furan is a clear and colorless liquid, and a bimolecular heterocycle, which can be used to trap unstable intermediates containing highly reactive species, via Diels-Alder cycloaddition reactions.
Furan, a naturally occurring compound associated with the flavor of food, is found at very low levels in a variety of food products and beverages. It finds applications as a solvent for resins and lacquers as well as in the preparation of organic compounds, in pharmaceuticals, etc. Furan is also reportedly identified in heat treated food products, including cooked chicken, fish protein concentrate, caramel back, canned meat, bread, coffee, etc.
This compound is listed in the SVHC (Substances of very high concern) candidate list of ECHA (European Chemicals Agency)
应用
Furan can undergo Diels-Alder [4+2] cycloaddition reaction with maleic anhydride to form the corresponding exo and endo furan-maleic anhydride adducts.
Furan may be used as an analytical reference standard for the quantification of the analyte in heat-processed foods using gas chromatography-mass spectrometry (GC-MS).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

In South Africa, 26-50% of households use solid fuel for cooking food and heating houses. When used as fuel, wood and chlorinated waste are known sources of polychlorinated dibenzo-para-dioxins, polychlorinated dibenzofurans (PCDD/Fs), and polychlorinated biphenyls (PCBs). Here, we compare PCDD/F
