Alpha-hydroxyhippuric acid is utilized in various biochemical and medical research applications due to its role as a metabolite. It is often studied in the context of metabolic pathways, particularly in understanding the metabolism of aromatic compounds in the human body. This compound is also used in clinical settings to assess kidney function, as it is excreted in urine and can serve as a marker for renal efficiency. Additionally, it has been explored in the development of diagnostic tools for detecting metabolic disorders related to amino acid and organic acid metabolism. In cosmetic and dermatological research, alpha-hydroxyhippuric acid derivatives are sometimes investigated for their potential skin-exfoliating and moisturizing properties, contributing to formulations aimed at improving skin texture and appearance.
