The tridecanoate is a saturated long-chain fatty acid with an odd number of carbon atoms and belongs to the group of alkanoic acids.

Occurrence

Like most long-chain fatty acids with odd carbon number comes tridecanoate in nature only rarely and in low concentration.

So she was found, for example, with shares of 0.24% to 0.64 % of the total fatty acids in some freshwater species of cyanobacteria. Also found in some vegetable oils contain low levels of tridecanoate, as to 0.07 % in the leaf oil of Cuban Ruta graveolens and 0.3% in the Cuban star fruit Averrhoa carambola oil.

Main fatty acid is at a level of almost 90 % of the fatty acids in the seeds of the Australian plant Stackhousia tryonii.

Production and representation

Tridecanoic acid can be prepared by oxidation of 1- tetradecene with potassium permanganate.

Use

Tridecanoic acid is up to 8 % is used in concentrations in perfume concentrates. Because of their rareness and of their low abundance in biological materials, it is also widely used in the gas chromatographic analysis of fatty acids as an internal standard.
