Description

(S)-4-(1-Boc-Amino-Ethyl)-Benzoic Acid Methyl Ester is a high-purity, chiral building block of significant importance in advanced organic synthesis. This compound serves as a critical intermediate for the development of novel active pharmaceutical ingredients (APIs) and fine chemicals, where stereochemical control is paramount. It is primarily needed by research institutions, pharmaceutical development labs, and fine chemical manufacturers engaged in the synthesis of complex molecules, particularly in medicinal chemistry and process development.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of new drug candidates, particularly for small molecule therapeutics.
• Peptidomimetic Synthesis: Used in the construction of peptide analogs and mimetics where the (S)-configured amino acid derivative is required.
• Ligand and Catalyst Development: Serves as a precursor for creating chiral ligands and organocatalysts used in asymmetric synthesis.
• Chemical Biology Probes: Employed in the synthesis of labeled or modified compounds for studying biological mechanisms and pathways.
• Custom Synthesis and Contract Manufacturing: A valuable starting material for custom synthesis projects requiring enantiomerically pure benzoic acid derivatives.
• Academic Research: Utilized in university and institutional labs for methodological development in stereoselective organic chemistry.

Quality Control

Our (S)-4-(1-Boc-Amino-Ethyl)-Benzoic Acid Methyl Ester is manufactured under strict quality management systems to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is subjected to rigorous analytical testing, including chiral HPLC for enantiomeric excess (ee) determination, NMR, and mass spectrometry for structural confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 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 desiccants.
