Description

L-Alanine, n-(Cyclopentylcarbonyl)-, Methyl Ester (9Ci) is a high-purity, non-natural amino acid derivative characterized by its alanine backbone modified with a cyclopentylcarbonyl group and a methyl ester. This specific molecular architecture makes it a valuable chiral building block and intermediate in advanced organic synthesis. It is primarily utilized by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs), peptide mimetics, and other fine chemicals where precise stereochemistry and functional group manipulation are critical.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of new therapeutic compounds, particularly in peptide-based drug discovery.
• Peptidomimetics Synthesis: Used to construct modified peptide structures that mimic natural peptides but with enhanced metabolic stability or bioavailability.
• Chemical Biology Research: Acts as a specialized probe or building block in studying enzyme mechanisms, protein-protein interactions, and metabolic pathways.
• Asymmetric Synthesis: Employed as a starting material or auxiliary in catalytic asymmetric reactions to introduce stereogenic centers into complex molecules.
• Agrochemical Development: Potential intermediate in the synthesis of advanced, chiral active ingredients for crop protection products.

Quality Control

Our L-Alanine, n-(Cyclopentylcarbonyl)-, Methyl Ester (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for research and pharmaceutical applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and other critical parameters.

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 compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed to prevent degradation from atmospheric moisture.
