As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. HPLC of Formula: C7H9N, Name is 2,4-Dimethylpyridine, belongs to chiral-nitrogen-ligands compound, is a common compound. HPLC of Formula: C7H9NCatalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In an article, authors is You, Jinmao, once mentioned the new application about HPLC of Formula: C7H9N.

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 HPLC of Formula: C7H9N
