This organic compound is insoluble in sodium hydroxide.

Eugenol is an organic compound with a strong aroma and is commonly used in the food, pharmaceutical and spice industries. However, it is insoluble in sodium hydroxide solution because there are no active groups in the molecular structure of eugenol that can react with sodium hydroxide.

Therefore, when preparing or processing eugenol, the use of sodium hydroxide as a solvent should be avoided, and other suitable organic solvents or co-solvents can be selected.
