PRODUCT INTRODUCTION
description
(R)-pantolactone is a butan-4-olide that is dihydrofuran-2(3H)-one substituted by a hydroxy group at position 3 and two methyl groups at position 4 (the R-stereoisomer). It has a role as a Saccharomyces cerevisiae metabolite. It is functionally related to a (R)-pantoic acid.
