QUICK LINKS

(R)-(+)-Citronellal is an organic compound found naturally and can be synthesized through an asymmetric synthesis reaction. It exhibits an optimal pH of 7. When citronellal reacts with caffeine, it forms citronellyl caffeate, a product that demonstrates synergistic effects in inhibiting bacterial growth. As a monoterpene compound derived from plant metabolism, (R)-(+)-Citronellal acts as a natural insect repellent and serves as the primary constituent of citronellal oil.
