Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If predominantly aliphatic chain structure
Non-aromatic peroxides separate subheading; aromaticity determined by principal ring structure.
If percarboxylic acid classification
Chapter 29 notes prioritize later headings; peracids may supersede simple peroxides.
If sold as formulated catalyst package
Antiknock preparations exclude pure compounds; presentation determines classification.
