TL;DR this compound won't be a GHB/GABAergic type sedative, because it is unable to make it across the membrane called the blood-brain barrier. The BBB, as it is called, can usually only be 'crossed' by drugs which can dissolve through the fatty membrane (or be sucked up by little pumps that move certain moecules across it). So compounds that are more "oily" and "fat soluble" (less
polar) will enter the brain much easier than compounds that are closer to behaving like water. (electrically charged compounds, acids, etc)
This compound is not very fat soluble, because it is an acid with lots of hydroxyl groups on it (OH groups), which makes it chemically closer to a very water soluble compound like sugar, rather than a "druglike" compound like THC.
Basically, this compound is too water soluble. You will just pee it out and it won't fuck you up.
