Boranes (Dimethylsulfide Borane, Borane-Tetrahydrofuran Complex) Borane-tetrahydrofuran (BTHF) and borane-dimethyl sulfide (BMS, DMSB) are often used as a borane source. Both reagents are available in solution (e.g. 1 M in THF), and are therefore easier to handle than diborane. Volatility and flammability are always a drawback. BMS is more stable than BTHF but has an unpleasant odor.
Apr 20, 2019· For all uses of dimethyl sulfoxide: Irritation where dimethyl sulfoxide is used. Bladder irrigation: Skin odor and breath odor like a garlic-like taste has happened with dimethyl sulfoxide. This may last for up to 72 hours after you get dimethyl sulfoxide. These are …
Stable, but highly flammable. Incompatible with oxidizing agents, strongacids, strong bases. May form explosive peroxides in storage, so often suppliedwith an inhibitor added.
Peroxide-forming chemicals are a class of compounds that have the ability to form shock-sensitive explosive peroxide crystals. Many of the organic solvents commonly used in laboratories have the potential to form explosive peroxide crystals. Diethyl ether and tetrahydrofuran are two of the more common peroxide-forming chemicals used today.

Tetrahydrofuran is a colorless liquid with an Ether-like odor. It is used as a monomer, a solvent for natural and synthetic resins, and a chemical intermediate. REASON FOR CITATION. * Tetrahydrofuran is on the Hazardous Substance List because it is regulated by OSHA and …
Tetrahydrofuran, the abbreviation of THF, is a heterocyclic organic compound. It belongs to ethers and is the fully hydrogenated product of the aromatic compound furan. It can be used as an aprotic solvent with moderate polarity in chemical reaction and solvent extraction. Tetrahydrofuran is a colorless, low viscosity liquid with a similar smell as ether.

Tetrahydrofuran (THF) is an organic compound with the formula (CH 2) 4 O. The compound is classified as heterocyclic compound, specifically a cyclic ether.It is a colorless, water-miscible organic liquid with low viscosity.It is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent.
Functional use(s) - flavoring agents. Has an sulfurous type odor.
While a few tetrahydrofuran derivatives such as galbacin, a 2,5-diaryl-3,4-dimethyl-tetrahydrofuran, occur amongst the lignans 〈78FOR(35)1〉, by far the main impetus in this area has come from carbohydrate chemistry. Pyranose sugars, with their six-membered rings in distinct chair or boat conformations, are readily probed by NMR methods but .
Borane-tetrahydrofuran complex is an important reagent used in the reduction of certain functional groups viz. aldehyde, ketone, carboxylic acid, amide, oxime, imine and nitrile. It is also used as hydro borating agent. It acts as a borane source for oxazaborolidine catalyzed asymmetric reductions.

Borane dimethylsulfide (BMS) is a complexed borane reagent that is used for hydroborations and reductions.The advantages of BMS over other borane reagents, such as borane-tetrahydrofuran, are its increased stability and higher solubility. BMS is commercially available at much higher concentrations than its tetrahydrofuran counterpart (10 M neat) and does not require sodium borohydride as a .

2,5-Furandicarboxylic acid is an organic chemical compound consisting of two carboxylic acid groups attached to a central furan ring. It was first reported as dehydromucic acid by Rudolph Fittig and Heinzelmann in 1876, who produced it via the action of concentrated hydrobromic acid upon mucic acid. It can be produced from certain carbohydrates and as such is a renewable resource, it was identified …
