Sucrose aromatic monocarboxylate

The present invention provides an ester of sucrose and an aromatic monocarboxylic acid represented by the general formula (I) with a small content of specific impurities. (In the formula, R 1 to R 5 are each independently a group selected from a hydrogen atom, an alkyl group, and an alkoxy group). This ester with a low halogen content has excellent compatibility with non-crystalline resins or crystalline resins, and can be used to improve its moldability, physical properties, softness, impact resistance, and other properties, and it has good thermal stability to suppress coloration due to heating. Resin modifier. This ester having a small amount of furanal and hydroxymethylfuranal can be effectively used as an odor-improving bulking agent that can improve the odor without reducing the bonding performance of the 2-cyanoacrylate-based adhesive.
