Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported in dilute solution exceeding transport safety limits
Diluted peroxides may shift to saturated acyclic monocarboxylic acid derivatives if solvent renders suitable for specific use.
If formulated as prepared chemical for specific industrial application
Mixtures exceeding simple stabilizer additions fall under chemical preparations rather than pure compounds.
