Medchemexpress LLC Acetaminophen-d4 | 64315-36-2 | 99.6% | C8H5D4NO2 | 5 MG
SDP

Acetaminophen-d4 is a deuterium-labeled version of Acetaminophen (Paracetamol). Acetaminophen is known as a selective cyclooxygenase-2 (COX-2) inhibitor with an IC50 of 25.8 μM and is a widely used antipyretic and analgesic. It also acts as a potent hepatic N-acetyltransferase 2 (NAT2) inhibitor. The compound is intended for research use only.

  • Deuterium labeled compound for tracing and quantitative analysis
  • Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
  • Stable heavy isotopes can affect pharmacokinetic and metabolic profiles of drugs
