Deuterated Piperidine-d11 from Mexico
Deuterated Piperidine-d11 is piperidine in which all 11 hydrogen atoms are replaced by deuterium, an isotope of hydrogen. It is used primarily as a solvent or reference standard in NMR spectroscopy. Under Chapter Note 1(a), isotopically substituted organic compounds are classified as the same chemically defined compound as the non-deuterated form, so it falls under tariff item 2933.32.00.
