Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derivatized as quinone rather than diol
Oxidized form (p-benzoquinone) classified as ketone-alcohol with oxygen function in 2914, not as phenol.
If put up as color developer for retail sale
Synthetic organic products used as developers for specific photographic use fall under Chapter 32.
If containing heterocyclic ring structure
Nucleic acid derivatives or other heterocyclics move to Chapter 29 subchapter for heterocyclic compounds.
