Used as a key intermediate in biochemical research, particularly in studies involving aromatic compound metabolism. It serves as a substrate for enzymes such as benzoyl-CoA reductase and is involved in anaerobic degradation pathways of aromatic compounds. Widely applied in enzymatic assays and metabolic pathway analysis, especially in microbiological systems where aromatic ring reduction occurs. Its lithium salt form enhances solubility and stability in aqueous reaction mixtures, making it suitable for in vitro studies. Also utilized in biotechnology for engineering microbial strains capable of degrading environmental pollutants.
