Definition:The (1R,1'S,2S,2'R) isomer of 2,2'-[(1,4-dioxobutane-1,4-diyl)bis(oxypropane-3,1-diyl)]bis[6,7,8-trimethoxy-2-methyl-1-(3,4,5-trimethoxybenzyl)-1,2,3,4-tetrahydroisoquinolinium]. It is the meso-isomer which has a trans configuration at the 1 and 2 positions of the tetrahydroisoquinolinium rings.
