Description

Diethyl 2-(((9H-Fluoren-9-Yl)Methoxy)Carbonyloxyimino)-2-C is a specialized Fmoc-protected amino acid derivative, a critical building block in modern peptide synthesis. Its primary value lies in enabling the controlled, sequential assembly of complex peptides by providing a protected amino acid precursor that is stable under standard coupling conditions but readily deprotected. This compound is essential for researchers and manufacturers in the pharmaceutical and biotechnology sectors who require high-purity intermediates for the development of therapeutic peptides, peptide hormones, and other bioactive molecules.

Application

• Solid-Phase Peptide Synthesis (SPPS): A key protected intermediate for the automated, stepwise construction of peptide chains using Fmoc chemistry.
• Pharmaceutical Research & Development: Used in the synthesis of novel peptide-based drug candidates and active pharmaceutical ingredients (APIs).
• Bioconjugation: Serves as a reagent for introducing specific amino acid functionalities into proteins, antibodies, or other biomolecules.
• Combinatorial Chemistry: Employed in libraries for high-throughput screening to discover new bioactive compounds.
• Academic Research: A fundamental reagent in university and institutional labs for studying peptide structure, function, and synthesis methodologies.
• Production of Custom Peptides: Used by CROs and CDMOs for the contract manufacturing of specific peptide sequences for clients.

Quality Control

Our Diethyl 2-(((9H-Fluoren-9-Yl)Methoxy)Carbonyloxyimino)-2-C is produced under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and KF titration for moisture content, to ensure it meets the exacting standards required for sensitive synthetic applications. Certificates of Analysis (COA) with full batch-specific data are provided to guarantee traceability, consistency, and reliability for your research and production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere (e.g., nitrogen or argon) after each use to prevent degradation. Keep away from heat and incompatible materials.
