2933.29.60.00 - Imidazole

This HTS category, 2933.29.60.00, specifically covers Imidazole. Imidazole is a five-membered heterocyclic aromatic organic compound with the chemical formula C₃H₄N₂. It features a planar ring structure containing two adjacent nitrogen atoms and three carbon atoms. Imidazole and its derivatives are fundamental building blocks in organic chemistry, playing crucial roles in pharmaceuticals, agrochemicals, and as ligands in coordination chemistry.

This classification distinguishes Imidazole from other compounds within the broader "Compounds containing an unfused imidazole ring (whether or not hydrogenated) in the structure" category. For instance, it is separate from the "Other" subcategory (2933.29.90.00) which would encompass other imidazole derivatives or compounds that do not precisely fit the specific listing of Imidazole itself as a distinct chemical entity.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification under 2933.29.60.00 is definitive for Imidazole when it is not further modified or combined in a manner that would necessitate classification under a more specific or different HTS heading. The focus remains on the pure chemical substance Imidazole, as defined by its chemical structure and common industrial and scientific applications.
