Description

4-(Cyclopropylamino)Butanoic Acid Ethyl Ester is a specialized organic building block featuring both a cyclopropylamine and an ester functional group. This unique bifunctional structure makes it a valuable intermediate for the synthesis of more complex molecules in advanced chemical research and development. It is primarily utilized by pharmaceutical and agrochemical R&D teams for constructing novel active ingredients and exploring new synthetic pathways.

Application

• Pharmaceutical Intermediate: A key synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly those targeting central nervous system (CNS) disorders or requiring cyclopropane ring incorporation.
• Agrochemical Synthesis: Serves as a versatile precursor in the design and synthesis of novel herbicides, fungicides, and insecticides with potentially enhanced efficacy and environmental profiles.
• Chemical Research & Development: Used as a model compound or starting material in organic synthesis for methodology development, exploring new cyclopropane-based reactions, and creating compound libraries.
• Fine Chemical Production: Employed in the multi-step synthesis of complex fine chemicals, flavors, and fragrances where the cyclopropyl moiety is a desired structural element.
• Ligand & Catalyst Development: The amine and ester functionalities make it a candidate for the preparation of novel ligands, organocatalysts, or metal-organic frameworks (MOFs) in materials science.

Quality Control

Our 4-(Cyclopropylamino)Butanoic Acid Ethyl Ester is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment and is available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
