Arachidonic Acid-13C5 methyl ester

Arachidonic acid-13C5 methyl ester is intended for use as an internal standard for the quantification of arachidonic acid methyl ester (Cay-90014) by GC- or LC-MS. Arachidonic acid methyl ester is an esterified form of arachidonic acid (Cay-90010, Cay-90010.1, Cay-10006607). It is commonly used as a reference standard for the quantification of arachidonic acid in biological samples and as a source of exogenous arachidonic acid in cells and in vivo.Formal Name: 5Z,8Z,11Z,14Z-eicosatetraenoic-1,2,3,4,5-13C5 acid, methyl ester.
