What is Citral CAS 5392-40-5?

Citral is a colorless or yellowish liquid with a strong lemon flavor. Optical inactivity. Boiling point 228℃, flash point 92℃. There are two isomers: cis and trans. With sodium bisulfite treatment, the cis solubility is very small, and the trans is very large, so the two can be separated. Cis-citral: Relative density (d200.8898), refractive index (nD20)1.4891, boiling point 118 ~ 119℃(2666Pa). Trans citral: relative density 0.8888, refractive index (nD20)1.4891, boiling point 117 ~ 118℃(2666Pa). Soluble in non-volatile oils, volatile oils, propylene glycol and ethanol, insoluble in glycerol and water. Unstable in basic and strong acids.
