| titleOfInvention | Alpha-cyano-4-hydroxycinnamic acid n-propyl, preparation method and application |
| abstract | Alpha-cyano-4-hydroxycinnamic acid n-propyl, preparation method and application, belong to substance assistant laser desorpted ionized mass spectrum (MALDI) technical field.Be under stirring at room temperature, in reaction solvent, add piperidines, then add cyanoacetic acid propyl ester and 4-hydroxy benzaldehyde, toluene is added again after medicine dissolves, stopped reaction after temperature rising reflux dewaters, after being then cooled to room temperature, revolving and steams containing the concentrated solution of alpha-cyano-4-hydroxycinnamic acid n-propyl; Product purification: gained concentrated solution is poured in a large amount of deionized water, have solid to separate out immediately, suction filtration obtains filter cake; Again by filter cake ethyl alcohol recrystallization 1 ~ 5 time, obtain micro-yellow product, i.e. alpha-cyano-4-hydroxycinnamic acid n-propyl.Adopt mass spectrometric analysis method of the present invention to detect all kinds of sample, sensitivity and detectability, compared with traditional matrices (alpha-cyano-4-hydroxycinnamic acid), have and better test effect. |
