Acetic anhydride and the Mexican opioid supply chain
Bloomberg reporting identified acetic anhydride supplied by Avantor and other companies as a chemical used by illicit drug producers to convert opium into heroin. The reporting raised questions about sales into Mexico, including the suitability of large containers for ordinary uses and the effectiveness of regulatory controls. Avantor stopped selling acetic anhydride in Mexico and destroyed remaining inventory. In 2021, U.S. Senator John Cornyn and other senators criticized the company’s apparent role in supplying a chemical connected to the opioid epidemic.
