Description

β-Ethylideneaspartate is a specialized aspartic acid derivative used as a key chiral building block and intermediate in advanced organic synthesis. This compound matters for its role in constructing complex molecules with high stereochemical purity, which is critical for developing active pharmaceutical ingredients (APIs) and fine chemicals. Industries that need it include pharmaceutical R&D, agrochemical manufacturing, and academic research focused on peptide mimetics and novel bioactive compounds.

Application

• Pharmaceutical Intermediate: A crucial chiral synthon for the synthesis of protease inhibitors, antiviral agents, and other small-molecule APIs.
• Agrochemical Synthesis: Used in the production of advanced herbicides and pesticides that require specific stereochemistry for optimal activity.
• Peptidomimetic Research: Serves as a constrained aspartate analog in the design and development of novel peptide-based therapeutics and diagnostic agents.
• Fine Chemical Production: Employed as a building block for specialty chemicals, flavors, and fragrances requiring high enantiomeric purity.
• Bioconjugation Chemistry: Acts as a linker or spacer molecule in the development of antibody-drug conjugates (ADCs) and other bioconjugates.
• Academic & Industrial R&D: A valuable reagent for methodological development in asymmetric synthesis and catalysis studies.

Quality Control

Our β-Ethylideneaspartate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request, supporting your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
