Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If impure or not exactly matching the named compound
Products not specifically listed as 3-Amino-3-methyl-1-butyne or the other named compound fall into the general 'Other' category in 2921.19.
If containing heterocyclic nitrogen atoms
If the molecule has a heterocyclic ring structure rather than purely acyclic, it shifts to Chapter 29 heterocyclic compounds.
If the amino group is substituted differently forming a halide derivative
Certain halogenated amine derivatives without prominent amine-function may classify under acyclic alcohols or derivatives.
