Recorded as (5Z,8Z,11Z,14Z,17Z)-ethyl nonadeca-5,8,11,14,17-pentaenoate, this compound is a nineteen-carbon fatty acid ethyl ester carrying five cis double bonds, and it belongs to the family of related substances studied alongside eicosapentaenoic acid and its ethyl ester. Its formula is C21H32O2 and its molecular weight is 316.48, and the material is a colourless liquid. Omega-3 laboratories use chain-length analogues of this sort to map impurity profiles in marine oil concentrates, to assign peaks in GC or LC analysis of fatty acid ethyl esters and to support method development for purity and related-substance testing where closely eluting homologues are hard to separate. The specified storage temperature is -80 C +/- 5 C and the product travels on dry ice. Pack sizes from 5 mg to 1 g appear in the specification list.
