Hazard Information

Description

Tridecylic acid, or tridecanoic acid, is a 13 - carbon saturated fatty acid with the chemical formula CH₃(CH₂)₁₁COOH. It is commonly found in dairy products.

Chemical Properties

off-white or white crystals or powder

Chemical Properties

White crystalline solid; waxy, woody aroma.

Occurrence

Reported found in star fruit oil Cuba (0.30%) and rue oil Cuba (0.07%).

Application

Tridecanoic acid has been used as an internal standard for the lipid analysis of total intramuscular fat from broilers and fatty acid analysis in chinook salmon roe lipids. It has also been used as a reference standard in gas chromatography for quantifying fatty acids in meat samples.

Definition

ChEBI: A C13 straight-chain saturated fatty acid.

Aroma threshold values

Medium strength odor, waxy type.

Synthesis Reference(s)

The Journal of Organic Chemistry, 35, p. 2846, 1970 DOI: 10.1021/jo00833a096

General Description

Tridecanoic acid is an aliphatic monoacid. It is complexed to β-cyclodextrin (β-CD) for structural studies. It can exist in three polymeric forms(A′, B′ and C′) when crystallized.

Purification Methods

Crystallise the acid from acetone. [Beilstein 2 IV 1117.]
