Description

(S)-Benzyl 2-Amino-2-Phenylethylcarbamate is a high-purity chiral intermediate of significant importance in asymmetric synthesis. Its primary value lies in serving as a key building block for the preparation of enantiomerically pure pharmaceuticals and bioactive compounds. This product is essential for research and development chemists and production units in the pharmaceutical, agrochemical, and fine chemical industries who require a reliable source of a stereochemically defined amino acid derivative.

Application

• Pharmaceutical Intermediate: Critical building block for the synthesis of chiral active pharmaceutical ingredients (APIs), particularly in neurologically active drugs and enzyme inhibitors.
• Peptide Synthesis: Used as a protected amino acid derivative in solid-phase and solution-phase peptide synthesis to introduce a phenylglycine moiety.
• Asymmetric Catalysis Research: Serves as a precursor or ligand in the development of novel chiral catalysts and auxiliaries.
• Agrochemical Synthesis: Intermediate in the production of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Academic & Industrial R&D: A valuable reagent for medicinal chemistry programs and process development for scale-up to commercial manufacturing.

Quality Control

Our (S)-Benzyl 2-Amino-2-Phenylethylcarbamate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent purity and chiral integrity standards suitable for pharmaceutical development. Certificates of Analysis (COA) detailing chiral purity (enantiomeric excess), chemical purity (by HPLC), and other critical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to exclude moisture. For long-term storage, consider using desiccants.
