Target Organs and Levels of Evidence for TR-554

Toxicology and Carcinogenesis Studies of 5-(Hydroxymethyl)-2-furfural (CASRN 67-47-0) in F344/N Rats and B6C3F1 Mice (Gavage Studies)

Chemical (Study Title)
CASRN
Peer Review DatePrimary UsesRoute/Exposure LevelsStudy Laboratory
5-(Hydroxymethyl)-2-furfural
67-47-0
02/27/2008A decomposition product of carbohydrates and is formed during cooking or heat sterilization of food. It has been identified in a wide variety of heat processed foods including milk, fruit juices, spirits, honey, etc. Associated with tobacco: reported either as a natural component of tobacco, pyrolysis product (in tobacco smoke), or additive for one or more types of tobacco products.Gavage
