dihydrokavain dihydrokavain dihydrokavain is one of the six major kavalactones found in the kava plant. it appears to contribute significantly to the anxiolytic effects of kava, based on a study in chicks. dihydrokavain names iupac name 4-methoxy-6-(2-phenylethyl)-5,6-dihydro-2h-pyran-2-one other names dihydrokawainmarindinin identifiers cas number 587-63-3 y 3d model (jsmol) interactive image chemspider 88817 n pubchem cid 98356 unii nw8zgw9xrz y comptox dashboard (epa) dtxsid8033433 inchi inchi=1s/c14h16o3/c1-16-13-9-12(17-14(15)10-13)8-7-11-5-3-2-4-6-11/h2-6,10,12h,7-9h2,1h3 nkey: vooytqrrepyriw-uhfffaoysa-n ninchi=1/c14h16o3/c1-16-13-9-12(17-14(15)10-13)8-7-11-5-3-2-4-6-11/h2-6,10,12h,7-9h2,1h3key: vooytqrrepyriw-uhfffaoyax smiles coc1=cc(=o)oc(c1)ccc2=cc=cc=c2 properties chemical formula c14h16o3 molar mass 232.27 g/mol except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). n verify (what is yn ?) infobox references dihydrokavain bears some structural similarity to the strobilurins and has some fungicidal activity.
