General description
Propyl 4-hydroxybenzoate (PHB), is a p-hydroxybenzoate derivative. It can be prepared by reacting p-hydroxybenzoic acid with n-propanol in the presence of an acidic ionic liquid.It crystallizes in the monoclinic space group P21/c.It is reported to be an endocrine disrupting compound.
Application
- Photostabilization of papaverine hydrochloride solutions.: This study investigates the use of Propyl 4-hydroxybenzoate to enhance the photostability of papaverine hydrochloride solutions. The research highlights the efficacy of Propyl 4-hydroxybenzoate as a preservative, providing insights into its potential applications in pharmaceuticals where light-induced degradation of compounds is a concern. The findings are significant for improving the shelf life and stability of medicinal solutions (Piotrowska K et al., 2010).
