Availabilty of METHYL ALCOHOL (more known as methanol CAS code 67-56-1), widely used as a reagent, solvent for glues and adhesives, in the pharmaceutical sector, inks and paints. It is also used for the degreasing of metals.Dollmar has availability of distribution in drums, IBC and bulks...
Since this seminal study, a great deal of the reaction chemistry of {Sm[N(SiMe3)2]2(THF)2} was used as a conduit to understand the reaction chemistry of SmI2. This reagent has a number of advantages since it is not as reactive as SmCp*2 [14], it is more soluble in lipophilic ...
Soluble in water, ethanol, ether,benzene and other organic solvents, known as "universal solvent". At room temperature, it is partially miscible with water energy, which is used by some illegal reagent merchants to make huge profits on THF reagent mixed with water. Since THF tends to form...
Methylamine can be used as a reagent in the synthesis of the following: Methylmorpholine from diethylene glycol. N -methylalkylamines from oxoamines via formation of imine, followed by hydrogenation using Ni catalyst. N -Methyldipropylenetriamine by reacting with acrylonitrile, followed by hydrogenation...
If variables W and Q of a particular compound of formula V represent removable protecting groups, removal of either or both groups followed by reaction of the resulting amine with an appropriate activated reagent will advantageously yield a different compound of formula V. For instance, reaction wit...
organic chemistryphysical chemistrytetrahydrofuran (THF)Progressive freezing technology was developed as a promising method to concentrate tetrahydrofuran (THF) remained in Grignard reagent wastewater. Effects of freezing temperature, ice formation rate, and seeding ice on ice purity were characterized. ...
