Quizalofop-P-Ethyl Herbicide
Quizalofop-P-ethyl, chemically 2-[4-[(6-chloro-2-quinoxalinyl)oxy]phenoxy]-propionic acid ethyl ester, is a selective post-emergence herbicide used primarily for grass weed control in broadleaf crops. It falls under HTS 2933.99.0200 as a specific aromatic heterocyclic compound with nitrogen hetero-atoms in a quinoxaline structure. This technical grade active ingredient is imported for formulation into agricultural pesticides.
Ethyl (R)-Quizalofop Technical Grade
The R-enantiomer of 2-[4-[(6-chloroquinoxalin-2-yl)oxy]phenoxy]propanoic acid ethyl ester, known as (R)-quizalofop-ethyl, is a high-purity chiral herbicide active ingredient. Classified under HTS 2933.99.0200 due to its specific named heterocyclic structure with nitrogen-only heteroatoms in the aromatic quinoxaline ring. Used in enantiopure formulations for enhanced selectivity in soybean and cotton weed control.
Quizalofop-P-Ethyl 97% TC Powder
Technical concentrate (TC) of quizalofop-P-ethyl at 97% purity, the named compound 2-[4-[(6-chloro-2-quinoxalinyl)oxy]phenoxy]propionic acid ethyl ester in powder form. HTS 2933.99.0200 applies as it's a separate chemically defined aromatic heterocyclic compound per Chapter 29 notes. Imported for dilution into emulsifiable concentrates for graminicide applications.
6-Chloro-2-(4-Hydroxyphenoxy)quinoxaline Ethyl Propionate
Synonym for quizalofop-P-ethyl, this specific ethyl ester of the propionic acid derivative with quinoxaline core is a named chemical under HTS 2933.99.0200. As an aromatic heterocyclic with only nitrogen hetero-atoms, it qualifies per Chapter 29 scope for separate organic compounds. Primarily imported as agrochemical intermediate.
