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.

Application

Citral is used in the preparation of artificial lemon oil, citrus oil, and other citrus flavors, fruit flavors, cherries, coffee, plums and other food flavors, and is also widely used in dishware detergent, soap, toilet water flavoring agent. Citral is the raw material for synthesis of ionone, methyl ionone and dihydrodamalone. As organic raw materials, it can be reduced to citronellol, nerolol and geraniol. It can also be converted to citronitrile. It is used in the pharmaceutical industry to manufacture vitamins A and E and is also the raw material of chlorophyl alcohol.
