General description

Citral is a mixture of neral (cis isomer of 3,7-dimethyl-2,6-octadienal) and geranial (trans isomer of 3,7-dimethyl-2,6-octadienal). It exhibits antimicrobial activity and pheromonal effects and is generally used for the synthesis of vitamin A and ionones.


  • Citral has been used as an anti-tumor agent against breast cancer cell lines (MCF-7 and MDA-MB-231).
  • It shows antipyretic effects which can be studied by systemic administration of lipopolysaccharide (LPS) to rats.
  • It can undergo 1,3-dipolar cycloaddition reaction with trimethylsilylazide to form 1,2,3-triazolines which possess pharmaceutical properties.

  5. What is the apparent molarity of Citral, Products W230316, C83007, and W230308?

    The apparent molarity of a neat liquid may be calculated from the density and molecular weight.  In the case of citral, the density is 0.888 g/mL and the molecular weight is 152.23 g/mole. By writing the density as 888 g/L, the calculation is 888 g/L divided by 152.23 g/mole = 5.83 mole/L, or 5.83 M.
