Products classified under HTS 2922.49.49.15
L-Aspartic Acid USP Grade
Pharmaceutical-grade L-aspartic acid meeting USP standards, a chemically defined amino acid used in drug formulations and nutritional supplements. It falls under HTS 2922.49.49.15 as a pure L-isomer of aspartic acid, an oxygen-function amino-acid other than those with multiple oxygen functions. This non-essential amino acid plays a key role in protein synthesis and metabolic pathways.
L-Aspartic Acid Food Grade
High-purity L-aspartic acid certified for food use as a nutritional additive and aspartame precursor. Classified under HTS 2922.49.49.15 as a separate chemically defined organic compound fitting oxygen-function amino-acid criteria. Meets FCC standards for safe incorporation into beverages, supplements, and fortified foods.
L-Aspartic Acid 99% Technical Grade
Technical-grade L-aspartic acid with 99% purity for industrial synthesis of pharmaceuticals and agrochemicals. Falls under HTS 2922.49.49.15 as a pure, separate L-aspartic acid molecule meeting Chapter 29 criteria for oxygen-function amino-acids. Used as chiral building block in peptide and polymer production.
L-Aspartic Acid Monohydrate Powder
L-Aspartic acid in monohydrate crystalline form (C4H7NO4·H2O) for pharmaceutical and supplement applications. Remains classified under HTS 2922.49.49.15 as the hydrate doesn't alter its chemical definition as pure L-aspartic acid. The water of crystallization is incidental per Chapter 29 solvent notes.
Pharma L-Aspartic Acid BP/EP Grade
European Pharmacopoeia (EP) and British Pharmacopoeia (BP) compliant L-aspartic acid for medicinal use. HTS 2922.49.49.15 applies to this chemically defined L-amino acid used in injectables and oral meds. Meets ICH Q7 GMP standards for API manufacturing.
