Metabolite Identification
Common Name3-tert-Butyl-4-hydroxyanisole
Description3-tert-Butyl-4-hydroxyanisole (3-BHA), also known as BHA or 4-methoxy-2-tert-butylphenol, belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. BHA is an extremely weak basic (essentially neutral) compound (based on its pKa). BHA is a waxy solid used as a food additive with the E number E320. BHA is a synthetic phenolic antioxidant (SPA). SPAs are a family of chemicals used widely in foods, polymers, and cosmetics as radical trapping agents to slow down degradation due to oxidation. Given their widespread use, human exposure is unavoidable and there is public concern regarding environmental contamination by these chemicals. BHA was detected in human urine (PMID: 31265952 ).
