Description

Homo-L-Tyrosine HBr is a high-purity, non-proteinogenic amino acid derivative, specifically the brominated salt form of homo-L-tyrosine. This compound serves as a critical chiral building block and intermediate in advanced organic synthesis and pharmaceutical research. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors who require high-quality, structurally defined intermediates for drug discovery and development.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of novel active pharmaceutical ingredients (APIs), particularly for neurological and metabolic disorders.
• Peptide Synthesis: Used as a modified tyrosine analog in solid-phase and solution-phase peptide synthesis to create peptides with enhanced stability or altered biological activity.
• Biochemical Research: Employed as a substrate or inhibitor in enzymatic studies and as a standard in analytical method development for amino acid analysis.
• Ligand and Probe Development: Acts as a precursor for synthesizing specialized ligands for receptor binding studies or fluorescent probes for cellular imaging.
• Fine Chemical Synthesis: Serves as a versatile building block for the synthesis of complex natural products, specialty chemicals, and advanced materials.
