Applications

Trichloroacetic anhydride is used as a derivatization reagent involved in the analysis of amphetamine,methamphetamine and 3,4-methylenedioxymethamphetamine. It is also used in the determination of the metabolites of l-alpha-acetylmethadol (LAAM), such as noracetylmethadol, dinoracetylmethadol, methadol and normethadol by electron capture gas-liquid chromatography. It is used in the synthesis of trichloroacetonylpyridine by reacting with 2-methyl-pyridine.

Notes

Moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong bases with strong oxidizing agents.
