Products classified under HTS 2933.29.10.00
2-Phenylimidazole
2-Phenylimidazole is a heterocyclic compound containing an unfused imidazole ring with a phenyl group at the 2-position, classified under HTS 2933.29.10.00 as an aromatic compound with nitrogen hetero-atom(s) only. It serves as a key intermediate in pharmaceutical synthesis and polymer chemistry.
High Purity 2-Phenylimidazole (99%+)
Pharmaceutical-grade 2-Phenylimidazole with purity exceeding 99%, used in antifungal drug synthesis and as a ligand in coordination chemistry. Falls under HTS 2933.29.10.00 due to its aromatic imidazole structure with phenyl substitution. Meets chapter requirements for separate chemically defined compounds.
2-Phenylimidazole Technical Grade
Technical grade 2-Phenylimidazole (95-98% purity) used in epoxy resin curing agents and corrosion inhibitors. Classified under HTS 2933.29.10.00 as it matches the specific description of aromatic 2-phenylimidazole. Excludes retail preparations per chapter exclusions.
2-Phenyl-4-Methylimidazole
A modified aromatic imidazole derivative with phenyl at 2-position and methyl substitution, used in photographic chemicals. HTS 2933.29.10.00 covers this as 'aromatic or modified aromatic' 2-phenylimidazole per statistical reporting. Qualifies as chemically defined heterocyclic compound.
2-Phenylimidazole Hydrochloride Salt
The hydrochloride salt form of 2-Phenylimidazole, water-soluble for pharmaceutical applications. Per chapter note on salts, classified with the parent organic base under HTS 2933.29.10.00. Used in antifungal creams and veterinary medicines.
Industrial 2-Phenylimidazole for Resin Curing
Bulk 2-Phenylimidazole packaged for epoxy resin curing applications in electronics. HTS 2933.29.10.00 applies as pure aromatic heterocyclic, not as finished resin (Chapter 39). Essential accelerator in circuit board manufacturing.
