Description

Alanine, Anhydride (9Ci) CAS NO 220190-44-3 is a specialized amino acid derivative where the carboxylic acid group of alanine is converted into an anhydride, a highly reactive functional group. This modification is critical for its primary role as a versatile building block in organic synthesis and peptide chemistry. It is an essential intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries, enabling the efficient creation of complex molecules and novel compounds.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), prodrugs, and novel therapeutic agents.
• Peptide Synthesis: Used as an activated amino acid derivative for coupling reactions in solid-phase and solution-phase peptide synthesis.
• Agrochemical Research: Serves as a building block for developing new pesticides, herbicides, and plant growth regulators.
• Bioconjugation & Labeling: Facilitates the attachment of alanine moieties or other functional groups to biomolecules like proteins or antibodies.
• Polymer Chemistry: Acts as a monomer or cross-linking agent for creating specialized polyamides or biodegradable polymers.
• Academic & R&D Laboratories: Employed in methodological development and as a standard reagent for studying anhydride reactivity.
• Fine Chemical Synthesis: Utilized in the multi-step synthesis of complex organic molecules, flavors, and fragrances.

Quality Control

Our Alanine, Anhydride is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory 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 (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition.
