IDENTIFIERS
126-15-8(4a(4H)-Dibenzofurancarboxaldehyde, 1,5a,6,9,9a,9b-hexahydro-)
USES/FORMS/SOURCES
R-11 is used as an insect repellent and is effective against cockroaches, nonbiting flies, gnats, and mosquitoes (HSDB). It is generally used in commercial formulations in combination with DEET (N,N-Diethyl-m-Toluamide) at concentrations in the range of 0.5 to 1% (HSDB).
2,3:4,5-bis-(2-BUTYLENE) TETRAHYDRO-2-FURALDEHYDE, also called R-11, is a pale yellow liquid with a fruity odor. It is insoluble in water, but is miscible with toluene, xylene, ethanol, and oils (HSDB).

GENERAL CLINICAL EFFECTS
- Editor's Note: An ERG guide with information appropriate to this material does not exist.
ACUTE CLINICAL EFFECTS
- Little is known about the toxicity of R-11. It was moderately toxic to rats, based on an oral LD50 of 2500 mg/kg (HSDB).
CHRONIC CLINICAL EFFECTS
- R-11 produced no obvious ill effects in a 90-day feeding study in rats receiving 20,000 mg/kg in the diet (HSDB).
