| titleOfInvention | Coumarin-pyridine compound, preparation method and application thereof |
| abstract | The invention discloses a coumarin-pyridine compound L, a preparation method and application thereof in H + Application in detection. The structural formula of the compound L is as follows: 6- (7-N, N-diethylaminocoumarin-3-yl) -2-methylpyridine-3-carboxylic acid ethyl ester. The compound is prepared by condensing coumarin ethanone serving as a raw material with DMFDMA to obtain an enaminone intermediate, and directly reacting the intermediate with ethyl acetoacetate in a series one-pot reaction without separation and purification. The compound L has a low pKa value for H + The kit has the obvious advantages of sensitive, quick and reversible response, good selectivity, strong anti-interference property, suitability for pH detection in a strong acid environment and the like, and has wide application prospects in environmental monitoring, ecological protection, disease diagnosis, industrial production and pollution discharge inspection. |
