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.

Originally identified as 4-methylaminoantipyrine by library match.
Jul 8, 2021: Identification of 4-Methylaminoantipyrine changed to Metamizole OR 4-Methylaminoantipyrine.
Cyan blue round tablet with 'M' on one side, break line and '30' on reverse. Counterfeit, bears markings that resemble an oxycodone tablet.
