Lab comments:
Regarding Metamizole / 4-Methylaminoantipyrine:

Our current GC/MS protocol can not distinguish between metamizole and 4-methylaminoantipyrine. 4-Methylaminoantipyrine is a metabolite of metamizole. Their mass spectra are indistinguishable because metamizole undergoes thermal decomposition to 4-methylaminoantipyrine and aminopyrine during GC-MS analysis. The chemical identified in this sample could be either Metamizole or 4-Methylaminoantipyrine, or a combination of the two.
Round light blue tablet with 'M' on one side, '30' and break line on the other. Counterfeit generic oxycodone.
Jul 7, 2021: Identification of Metamizole changed to Metamizole OR 4-Methylaminoantipyrine.
Cross-contamination Risk: Samples 9131 through 9140 were submitted together, it's possible that a chemical detected in this sample was a result of cross-contamination of samples prior to arriving at the lab.
