Butyrolactol A is a polyketide featuring a tert-butyl group linked to a long hydrophobic carbon chain followed by 8 polyol groups. It is one of a number of potentially useful substances derived from the bacteria Streptomyces rochei.

Research has shown that, using isotopic labeling of media and spectroscopic techniques to identify precursor products which are eventually incorporated into the final product, it can be created via a biosynthetic pathway. Further analysis of gene clusters encoding for biosynthetic enzymes confirmed the presence of polyketide synthesizing genes that are involved with the aforementioned pathways for this molecule.

Butyrolactol A is also of interest for its potential use as an antifungal antibiotic.
