Used in biochemical research for the study of phenolic compound metabolism, particularly in the degradation pathways of aromatic compounds. Facilitates the breakdown of protocatechuic acid in microbial systems, supporting investigations in bioremediation and carbon cycle processes. The lyophilized form ensures stability for storage and is suitable for enzyme activity assays, kinetic studies, and purification protocols in laboratory settings. Commonly employed in studies involving soil and environmental microbiology where aromatic acid transformation is analyzed.
