Found in some industrial biocides, preservatives, cleaning products, and hospital disinfectants due to its antimicrobial properties. Also used in small amounts in the formulation of certain pharmaceuticals, cosmetics to extend shelf life, and in research settings to study metabolic disorders and gut microbiome interactions. p-Cresol is toxic and should be handled with care, avoiding prolonged skin contact or inhalation.
