Benzyl Glycine
Benzyl glycine (2-amino-3-phenylpropanoic acid variant) is an aromatic-substituted glycine classified under HTS 2922.49.37.00 as other aromatic oxygen-function amino-compound. Single carboxyl function qualifies it for this heading. Used in custom peptide production.

Import Tips & Compliance
• Verify structure via MS/MS fragmentation confirming benzyl-alpha-amino pattern
• Small volume research chemicals need commercial invoice with research end-use statement
• Don't confuse with glycine (2922.49.1450); benzyl substitution makes aromatic

DL-Phenylalanine
DL-Phenylalanine is an aromatic amino acid containing a single carboxyl oxygen function, classified under HTS 2922.49.37.00 as an oxygen-function amino-compound that is neither a proteinogenic amino acid nor a drug. It is used as a nutritional supplement and in pharmaceutical intermediates. The code covers other aromatic amino acids and their simple derivatives not specified elsewhere.
DL-Tyrosine
DL-Tyrosine is a synthetic aromatic amino acid with phenolic oxygen function, falling under HTS 2922.49.37.00 as 'other' oxygen-function amino-compounds. Despite its phenolic group, it qualifies due to single carboxyl classification and exclusion from proteinogenic listings. Commonly used in nootropic supplements and biochemical research.
4-Fluorophenylalanine
4-Fluorophenylalanine is a halogenated aromatic amino acid used in PET imaging tracers and protein engineering, falling under HTS 2922.49.37.00. The fluorine substitution doesn't alter its oxygen-function amino-acid classification per chapter note 4. Qualifies as chemically defined compound of note (a).
3-Nitrophenylalanine
3-Nitrophenylalanine is a nitro-substituted aromatic amino acid used in photocaging groups for photochemistry, classified HTS 2922.49.37.00. Nitro group doesn't count as nitrogen-function for 2929 per chapter note 4. Single oxygen-function carboxyl defines classification.
D-Phenylalaninol
D-Phenylalaninol is the amino-alcohol reduction product of phenylalanine, classified under HTS 2922.49.37.00 as oxygen-function amino-compound (alcohol oxygen). Retains amino-acid carbon skeleton recognition. Used in chiral ligand synthesis.
Tyrosine Ethyl Ester
Tyrosine ethyl ester follows parent tyrosine classification per note 3(B) in HTS 2922.49.37.00. Ethyl esters of Chapter 29 acids stay with acid heading. Protected form for peptide synthesis.
