Description

3-Bromotyrosine is a halogenated derivative of the essential amino acid tyrosine, serving as a critical synthetic intermediate and biochemical research tool. Its primary value lies in its utility for introducing a bromine atom into complex molecules, enabling advanced organic synthesis and the study of protein structure and function. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and life science sectors, particularly for developing novel active ingredients and biochemical probes.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, including enzyme inhibitors and receptor modulators.
• Biochemical Research: Used in peptide synthesis to incorporate bromine labels for studying protein-protein interactions, enzyme mechanisms, and post-translational modifications.
• Agrochemical Development: Serves as a precursor in the creation of advanced herbicides, fungicides, and plant growth regulators.
• Proteomics & Labeling: Acts as a reagent for the selective bromination of tyrosine residues in proteins for mass spectrometry analysis and structural biology studies.
• Organic Synthesis: A versatile starting material for cross-coupling reactions (e.g., Suzuki, Heck) to construct complex biaryl and heterocyclic structures.
• Material Science: Potential monomer or modifier for creating specialized polymers with unique halogenated properties.

Quality Control

Our 3-Bromotyrosine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis for enantiomeric excess, and identity confirmation via IR and NMR spectroscopy. We provide Certificates of Analysis (COA) with each shipment, detailing all specifications. Production can be aligned with cGMP standards for advanced pharmaceutical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a low-humidity environment. For long-term storage, consider using desiccants.
