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 is a monoterpene aldehyde used as an aromatic ingredient in food and cosmetic industry.

Application

  • 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.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  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.

Increased bacterial resistance to food preservation technologies represents a risk for food safety and shelf-life. The use of natural antimicrobials, such as essential oils (EOs) and their individual constituents (ICs), has been proposed to avoid the generation of antimicrobial resistance.
