Products classified under HTS 2933.19.30.95
1-Phenyl-3-methyl-5-pyrazolone
A pyrazole derivative used as a key intermediate in the synthesis of photographic developers and dyes. This aromatic heterocyclic compound contains an unfused pyrazolone ring structure, qualifying it under HTS 2933.19.30 for photographic chemicals with pyrazole rings.
4-Amino-1-phenyl-3-pyrazolidinone
Pyrazolidinone derivative serving as a developing agent in black-and-white photographic processing. Its unfused pyrazole ring and aromatic substitution place it specifically under HTS 2933.19.30.95 for photographic chemicals.
3-Methyl-1-p-sulophenyl-5-pyrazolone
Sulfonated pyrazolone used in color photographic coupler chemistry and dye synthesis. The aromatic-modified pyrazole ring structure fits HTS 2933.19.30.95 specifications for photographic chemicals.
1-(2,4,6-Trichlorophenyl)-5-pyrazolone-3-carboxylic Acid
Chlorinated aromatic pyrazolone carboxylic acid used in specialty photographic sensitizers. Falls under HTS 2933.19.30.95 due to unfused pyrazole ring and photographic chemical designation.
Ethyl 5-oxo-1-phenyl-1H-pyrazole-3-carboxylate
Pyrazole carboxylate ester intermediate for photographic dye-formers and developers. The unfused pyrazole ring with aromatic modification qualifies under HTS 2933.19.30.95.
