The molecule is a carboxylic ester obtained by formal condensation of the carboxy group of (2S,3S)-2,3-dihydroxy-2-isopropylbutanoic acid with the hydroxy group of (7aS)-2,3,5,7a-tetrahydropyrrolizin-7-ylmethanol. It has a role as a plant metabolite. It is a member of pyrrolizines, a butyrate ester, a carboxylic ester, a secondary alcohol, a tertiary alcohol and a pyrrolizidine alkaloid.
