Reference of 39648-67-4, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 39648-67-4, Name is (R)-4-Hydroxydinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide, molecular formula is C20H13O4P. In a Article，once mentioned of 39648-67-4
Diquats with extremely high racemization barriers with DeltaG?theor of 233 kJ mol?1 at 180 C are described. Reported configurational robustness is due to a combination of two structural features: the rigid o-xylylene tether connecting the nitrogen atoms and the presence of two substituents in the bay region of the bipyridinium scaffold. The straightforward synthesis of diquats, plus facile resolution and derivatization make them attractive for chiral application studies. This is demonstrated by: 1) synthesis of the first non-racemic diquat dyes with pronounced chiroptical properties, and 2) capability of diquats to interact stereospecifically with chiral molecules. This suggests potential for diquat derivatives to be used as chiral selectors in separation methods.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 39648-67-4 is helpful to your research., Reference of 39648-67-4
