Citronella Extra Pure
Citronella Extra Pure is a laboratory-grade essential oil distilled primarily from Cymbopogon species, known for its strong, lemon-like aroma and high content of citronellal, geraniol, and citronellol. In lab settings, it is used in analytical chemistry, fragrance analysis, natural product research, and biological assays due to its volatile organic profile. The extra pure grade ensures the oil is free from synthetic additives and contaminants, offering consistent performance in both qualitative and quantitative studies. It also serves as a reference standard in olfactory testing and is handled with care due to its high volatility and sensitivity to light and air.
Primary Uses
