Quality Control of H-Phg-OEt.HClOn March 31, 2003, Vicente, Virginie; Fruchier, Alain; Cristau, Henri-Jean published an article in Magnetic Resonance in Chemistry. The article was 《Determination of 31P, 31P coupling constants in cyclotriphosphazenes and their influence on 1H and 13C NMR spectra of phosphorus substituents》. The article mentions the following:
1H and 13C NMR spectra of sym. substituted cyclotriphenylosphazenes exhibit second-order effect0. The influence of the 31P,31P coupling constants between ring P atoms on these effects was studied. Some values of this coupling constant between P bearing identical substituents were measured using 13C satellites of the 31P signals or by introduction of a chiral substituent on the third P atom. In the experiment, the researchers used H-Phg-OEt.HCl(cas: 59410-82-1Quality Control of H-Phg-OEt.HCl)
H-Phg-OEt.HCl(cas: 59410-82-1) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils.Quality Control of H-Phg-OEt.HCl They perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market.
