Products classified under HTS 2922.49.05.00
(R)-α-Aminobenzeneacetic acid
(R)-α-Aminobenzeneacetic acid, also known as D-phenylglycine, is a chiral aromatic amino acid featuring both amino and carboxylic acid oxygen functions on a benzene ring. It falls under HTS 2922.49.0500 as a specific aromatic amino acid with a single type of oxygen function (carboxyl group). This compound is primarily used as a key intermediate in synthesizing beta-lactam antibiotics like ampicillin.
2-Amino-3-chlorobenzoic acid methyl ester
This is the methyl ester of 2-amino-3-chlorobenzoic acid, an aromatic compound with amino-acid oxygen function and chlorine substitution. Specifically named in HTS 2922.49.0500 as an ester of an aromatic amino acid. Used as intermediate in dye and pharmaceutical synthesis.
D-Phenylglycine 98% Pharmaceutical Grade
High-purity (R)-α-Aminobenzeneacetic acid meeting USP standards for pharmaceutical manufacturing. Classified under HTS 2922.49.0500 due to its specific chemical identity as an aromatic amino acid. Used exclusively in synthesis of semisynthetic penicillins.
Methyl 2-Amino-3-chlorobenzoate Technical Grade
Technical grade 2-amino-3-chlorobenzoic acid methyl ester used in custom synthesis. Meets HTS 2922.49.0500 specificity as aromatic amino-acid ester. Intermediate for pharmaceutical and agrochemical applications.
(R)-Phenylglycine Free Acid
The free acid form of D-phenylglycine, a critical chirality center for beta-lactam synthesis. HTS 2922.49.0500 explicitly names this aromatic α-amino acid. Supplied as white crystalline powder with high enantiomeric excess.
