Products classified under HTS 2924.19.11.20
Dimethylformamide (DMF) 99.9% Pure
Dimethylformamide (DMF), chemically N,N-dimethylformamide (CAS 68-12-2), is a colorless liquid amide used as a versatile aprotic solvent in chemical reactions and polymer processing. It falls under HTS 2924.19.11.20 as a chemically defined acyclic amide, specifically the amide of formic acid with dimethylamine, meeting Chapter 29 note (a).
Industrial Grade Dimethylformamide DMF
Industrial-grade DMF is a high-volume solvent for polyurethane production and fiber spinning, characterized by its high boiling point and miscibility with water. Classified under HTS 2924.19.11.20 as the specific acyclic amide dimethylformamide per Chapter 29 definitions.
Pharmaceutical Grade Dimethylformamide
Pharma-grade DMF meets USP/EP standards for use in drug synthesis and peptide manufacturing, ensuring low impurity levels. It is specifically dimethylformamide, an acyclic amide, directly under HTS 2924.19.11.20.
Anhydrous Dimethylformamide Solvent
Anhydrous DMF is water-free for moisture-sensitive reactions like Grignard setups in organic synthesis. As pure N,N-dimethylformamide, it qualifies under HTS 2924.19.11.20 for acyclic amides.
DMF for Polyacrylonitrile Fiber Production
Specialty DMF used in the solvent-spinning process for acrylic fibers, offering high solvency for polymers. It is the chemically defined compound dimethylformamide under HTS 2924.19.11.20.
