Used primarily in biochemical research to study metabolic processes, particularly those involving the breakdown of aromatic compounds in the body. It serves as a biomarker for assessing exposure to certain environmental chemicals by measuring its levels in urine. Additionally, it aids in understanding the detoxification pathways in the liver and kidneys, providing insights into how the body processes and eliminates toxins. Its role in metabolic studies helps in diagnosing and monitoring conditions related to impaired detoxification mechanisms.
