Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 108-47-4. SDS of cas: 108-47-4

In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system. SDS of cas: 108-47-4,108-47-4, name is 2,4-Dimethylpyridine. In an article，Which mentioned a new discovery about 108-47-4

A simple and sensitive method for the determination of short and long-chain fatty acids using high-performance liquid chromatography with fluorimetric detection has been developed. The fatty acids were derivatized to their corresponding esters with 9-(2-hydroxyethyl)-carbazole (HEC) in acetonitrile at 60C with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride as a coupling agent in the presence of 4-dimethylaminopyridine (DMAP). A mixture of esters of C1-C20 fatty acids was completely separated within 38 min in conjunction with a gradient elution on a reversed-phase C18 column. The maximum fluorescence emission for the derivatized fatty acids is at 365 nm (lambdaex 335 nm). Studies on derivatization conditions indicate that fatty acids react proceeded rapidly and smoothly with HEC in the presence of EDC and DMAP in acetonitrile to give the corresponding sensitively fluorescent derivatives. The application of this method to the analysis of long chain fatty acids in plasma is also investigated. The LC separation shows good selectivity and reproducibility for fatty acids derivatives. The R.S.D. (n = 6) for each fatty acid derivative are <4%. The detection limits are at 45-68 fmol levels for C14-C20 fatty acids and even lower levels for SDS of cas: 108-47-4
