The highest THF value in the blood was at 1 hr post-application (about 200 mg/kg). The biological half-life in blood was 5 hr. THF concentrations in adipose tissue and kidneys were 1.3-1.4 times higher than in blood; levels in liver, brain, spleen, and muscle were similar to blood.

Sigma-Aldrich offers Sigma-Aldrich-401757, Tetrahydrofuran (THF) for your research needs. Find product specific information including CAS, MSDS, protocols and references.

THF is renowned in organic chemistry for its role as a solvent, especially in substitution reactions, such as the S N 2 mechanism. The S N 2 reaction is a type of substitution reaction where a nucleophile (“nucleus-loving”) atom or molecule displaces a group (the leaving group) in …

2015年7月28日 · Tetrahydrofuran (THF, oxolane) is a versatile solvent used in laboratory organic synthesis and in industrial products such as varnishes. It is colorless and miscible in water, with a boiling point of 66 ºC.

A violent explosion occurred during the preparation of sodium aluminum hydride from sodium and aluminum in a medium of tetrahydrofuran [Chem. Eng. News 39(40):57. 1961]. THF forms explosive products with 2-aminophenol [Lewis 3227].

Diethylene oxide, 1,4-Epoxybutane, Tetramethylene oxide, THF Colorless liquid with an ether-like odor.

Tetrahydrofuran, or THF, is a colorless liquid and a moderate polar aprotic solvent. It’s considered a heterocyclic compound that includes oxygen. This oxygen atom can accept hydrogen bonding, making the compound very water soluble. THF can dissolve many organic compounds.

2024年7月25日 · Tetrahydrofuran (THF), also known as oxolane, is a cyclic ether with the chemical formula C4H8O. It has a wide application in the chemical industry.

Tetrahydrofuran (THF) is a highly versatile organic solvent belonging to the ether family. It is a colorless liquid with a characteristic mild odor and excellent solubility properties. THF is widely used in industrial processes, laboratory research, and the production of polymers due to its role as a solvent and chemical intermediate.
