What is Tridecanal?

Chemical properties

clear faint yellow liquid

Chemical properties

Tridecanal occurs in lemon oil and has been identified as a volatile constituent of cucumber. It is a colorless liquid having a fatty, waxy, slightly citrus-like odor. Addition of tridecanal to fragrance compositions imparts fresh nuances in the top note as well as in the dry-out.

Chemical properties

Colorless clear liquid; fresh, clean, aldehydic, soapy, citrus, petal, waxy, grapefruit peel aroma.

Occurrence

Reported found in angelica seed oil CO2 extract (0.50%), blood orange oil (Citrus senensis L. var. Sanguinello) Italy (trace), blood orange oil (Citrus senensis L. var. Tarocco) Italy (trace), blood orange oil Italy (trace), cistus oil (0.1%), coriander leaf oil (1.43–1.44%), Herniaria incana Lam. oil Greece (5.80%), orange peel oil sweet c.p. blond Italy (trace), and witch hazel leaf oil (0.24%).

The Uses of Tridecanal

Tridecanal is a model compound in the nonradioactive assay/RP-HPLC-fluorescence analysis of aliphatic aldehydes employing the Hantzsch reaction.

Definition

ChEBI: Tridecanal is a long-chain fatty aldehyde that is tridecane in which two hydrogens attached to a terminal carbon are replaced by an oxo group. It has a role as a human metabolite and a volatile oil component. It is a saturated fatty aldehyde, a n-alkanal and a long-chain fatty aldehyde. It derives from a hydride of a tridecane.

Aroma threshold values

Aldehydic type, high strength odor; recommend smelling in a 1.00% solution or less.

General Description

The uptake of NO(3) on solid tridecanal was studied.
