Description

Boc-Dl-o-Tyrosine is a protected derivative of the amino acid tyrosine, featuring a tert-butoxycarbonyl (Boc) group on the amine functionality. This modification is critical for its primary role as a key synthetic intermediate in the production of peptides and other complex organic molecules. It is essential for research and development laboratories, pharmaceutical manufacturers, and fine chemical synthesis companies engaged in peptide chemistry and drug discovery. The compound is supplied to meet the stringent purity requirements of advanced chemical synthesis.

Application

• Peptide Synthesis: Serves as a crucial building block (amino acid derivative) in solid-phase and solution-phase peptide synthesis, where the Boc group provides temporary amine protection.
• Pharmaceutical Intermediates: Used in the research and development of novel therapeutic peptides and peptidomimetics targeting various diseases.
• Biochemical Research: Employed in studies involving protein structure, enzyme-substrate interactions, and the development of biochemical probes.
• Fine Chemical Production: Acts as a specialized intermediate in the multi-step synthesis of complex organic compounds and active pharmaceutical ingredients (APIs).
• Protecting Group Chemistry: Utilized in methodological studies and synthetic routes that require orthogonal protection strategies for amino acids.

Quality Control

Our Boc-Dl-o-Tyrosine is manufactured under a quality management system and undergoes rigorous analytical testing to ensure batch-to-batch consistency and high purity. Standard quality control includes assessment by HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment. We can support development projects requiring specific analytical specifications or compliance with cGMP guidelines for advanced intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using a desiccant.
