N-(3-Carboxy-1-oxopropyl)-L-tyrosine, with CAS number 374816-32-7, is a tyrosine derivative featuring a succinamic acid moiety. It is a modified amino acid where the amino group of L-tyrosine is acylated with a succinic acid half-amide group. This structure imparts specific chemical properties, making it a valuable building block in peptide and peptidomimetic chemistry. This compound is primarily used in life science research and pharmaceutical development. It serves as a key intermediate or a specialized amino acid analog for the synthesis of modified peptides, enzyme substrates, or inhibitors. The presence of the free carboxylic acid and the phenolic hydroxyl group on the tyrosine side chain allows for further functionalization and conjugation, enabling its incorporation into larger bioactive molecules or probes designed to study biological processes.
