| Definition |
ChEBI: 5-hydroxymethylfurfural is a member of the class of furans that is furan which is substituted at positions 2 and 5 by formyl and hydroxymethyl substituents, respectively. Virtually absent from fresh foods, it is naturally generated in sugar-containing foods during storage, and especially by drying or cooking. It is the causative component in honey that affects the presystemic metabolism and pharmacokinetics of GZ in-vivo. It has a role as an indicator and a Maillard reaction product. It is a member of furans, an arenecarbaldehyde and a primary alcohol. |
| Application |
5-Hydroxymethylfurfural has been used as a standard in the high performance liquid chromatographic (HPLC) analysis for the determination of 5-(hydroxymethyl)furfural content in co-hydrolysates and fermentation broth of lignocellulosic biomass for the lipid accumulation in M. isabellina type of microorganisms. 5-(Hydroxymethyl)furfural may be used as an analytical reference standard for the quantification of the analyte in vinegar and fruit juice samples using chromatography techniques.

| Biological Activity |
5-Hydroxymethylfurfural is a furanic compound derived from the degradation of sugars. It can be derived from reducing sugars via acid-catalyzed degradation or the Maillard reaction during the heating and storage of foods. 5-Hydroxymethylfurfural is an intermediate in the synthesis of a variety of compounds including 2,5-diformylfuran (DFF), 2,5-furandicarboxylic acid (FDA), 2,5-bis(hydroxymethyl)furan (5-(hydroxymethyl)furfuryl alcohol; Item No. 20658), and dimethylfuran (DMF), among others. 5-Hydroxymethylfurfural has been found in the marine algae L. undulata and scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl, alkyl, and superoxide radicals in cell-free assays (IC50s = 27.1, 22.8, 45, and 33.5 μM, respectively). |
| Safety Profile |
Questionable carcinogen with experimental tumorigenic data.Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES |
| Safety |
5-Hydroxymethylfurfural is irritating to eyes, mucous membranes and skin, and has neurotoxicity and genotoxicity; it can be metabolized into 5-sulfoxymethylfurfural (SMF) in vivo, which has strong carcinogenicity and Genotoxicity. Chemical properties Light yellow waxy, easily soluble in methanol and ethanol, derived from Cornus, with high content of d-glucose. Uses for content determination/identification/pharmacological experiments, etc. |
| Metabolic pathway |
When 5-hydroxymethyl-2-furaldehyde (HMF) is administered orally or intravenously to rats, HMF or its metabolites are rapidly eliminated in the urine with the recovery of 95 100% after 24 h. HMF is completely converted to two metabolites which are identified as 5- hydroxymethyl-2-furoic acid and N-(5-hydroxymethyl-2- furoyl)glycine. |
| Purification Methods |
Crystallise it from diethyl ether/pet ether. [Beilstein 18 III/IV 100, 18/1 V 130.] |
| Toxicity evaluation |
5-Hydroxymethylfurfural (5-HMF) as a product of the Maillard reaction is found in many foods. Estimated intakes range between 4 and 30 mg per person and day, while an intake of up to 350 mg can result from, e.g., beverages made from dried plums. In vitro genotoxicity was positive when the metabolic preconditions for the formation of the reactive metabolite 5-sulphoxymethylfurfural were met. However, so far in vivo genotoxicity was negative. Results obtained in short-term model studies for 5-HMF on the induction of neoplastic changes in the intestinal tract were negative or cannot be reliably interpreted as “carcinogenic”. In the only long-term carcinogenicity study in rats and mice no tumours or their precursory stages were induced by 5-HMF aside from liver adenomas in female mice, the relevance of which must be viewed as doubtful. Hence, no relevance for humans concerning carcinogenic and genotoxic effects can be derived. The remaining toxic potential is rather low. Various animal experiments reveal that no adverse effect levels are in the range of 80–100 mg/kg body weight and day. Safety margins are generally sufficient. However, 5-HMF exposure resulting from caramel colours used as food additives should be further evaluated.
