Lab comments:
Analyzed twice.

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.
