    Product Description

    4(Z),7(Z),10(Z),13(Z),16(Z)-Nonadecapentaenoic acid-d5 is intended for use as an internal standard for the quantification of 4(Z),7(Z),10(Z),13(Z),16(Z)-nonadecapentaenoic acid by GC- or LC-MS. 4(Z),7(Z),10(Z),13(Z),16(Z)-Nonadecapentaenoic acid (19:5 n-3) is an impurity generated during the synthesis of docosahexaenoic acid-d5 (Item No. 10005057). While the physiological properties of this compound are not known, dietary intake of n-3 long chain polyunsaturated fatty acids provides potential health benefits.1
