L-Lysine Acetate
L-Lysine acetate is the acetic acid salt of L-lysine, used primarily in cell culture media and biopharmaceutical production as a stable, soluble amino acid source. Classified under 2922.41.00.90 as an 'other' ester/salt of lysine per Chapter 29 notes on organic salts. Its single carboxyl oxygen function defines it as a basic amino acid derivative.

L-Lysine Monohydrochloride
L-Lysine monohydrochloride is the hydrochloride salt of the essential amino acid L-lysine, a chemically defined organic compound with an amino-acid oxygen function (carboxyl group). It falls under HTS 2922.41.00.90 as 'other' lysine salts, distinct from the principal L-lysine HCl used in animal feed. Primarily used in pharmaceuticals and nutritional supplements for human consumption.
Epsilon-Acetyl-L-Lysine
Epsilon-acetyl-L-lysine is a chemically modified lysine where the epsilon-amino group is acetylated, used in biochemical research and peptide synthesis. It remains classified under 2922.41.00.90 as a lysine derivative salt/ester with retained principal amino-acid characteristics and single oxygen function.
DL-Lysine Hydrochloride
DL-Lysine hydrochloride is the racemic mixture salt of D- and L-lysine, used in research and as a chemical intermediate rather than nutrition. It qualifies under HTS 2922.41.00.90 as 'other' lysine salts, meeting Chapter 29's definition for chemically defined amino acid salts with single oxygen function.
L-Lysine Sulfate
L-Lysine sulfate (2:1 lysine to sulfuric acid) is an alternative salt form to hydrochloride, used in specialized nutritional and pharmaceutical applications requiring lower chloride content. Falls under 2922.41.00.90 as 'other' lysine salts per Chapter 29 note (C)(1) on organic salts classification.
L-Lysine Ethyl Ester Dihydrochloride
L-Lysine ethyl ester dihydrochloride is the diethyl ester salt of lysine, an intermediate in organic synthesis and pharmaceutical manufacturing. Per Chapter 29 note on esters, it classifies with the parent lysine under 2922.41.00.90 as 'other' esters/salts.
