Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified by primary amine function
If amine functionality dominates over heterocyclic structure, it may fall under carboxylic acid amides.
If when imported with added stabilizers for safety
Stabilized preparations exceeding simple chemical scope classify as other organic compounds.
If pre-formulated into developer concentrates
Chapter 37 covers finished photographic chemicals, not pure intermediates.
