Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing sugar moiety or classified as antibiotic derivative
Antibiotics and derivatives have specific Chapter 29 heading taking precedence over general thiazoles.
If oxygen heterocyclic function emphasized over thiazole
Imine/oxime functions might classify under 2933 but thiazole takes last numerical order per note.
If for industrial end-use as carboxamide derivative
Carboxyamide-function compounds in 2924 could apply if thiazole not principal characteristic.
