Nguyen, Van Hai published the artcilePropyl gallate, Recommanded Product: Propyl 3,4,5-trihydroxybenzoate, the publication is Molbank (2021), M1201, database is CAplus.
The title compound, Pr gallate (III), is an important substance popularly used in the food, cosmetic and pharmaceutical industries. Current chem. syntheses of this compound are based on the acylation supported by thionyl chloride, DIC/DMAP or Fischer esterification using a range of homogenous and heterogenous catalysts. In this paper, an efficient, green, straightforward, and economical method for synthesizing Pr gallate using potassium hydrogen sulfate, KHSO4, as the heterogenous acidic catalyst has been developed for the first time. In addition, this paper provides a comprehensive spectral dataset for the title compound, especially the new data on DEPT and 2D NMR (HSQC and HMBC) spectra which are not currently available in the literature.
