Description

Dl-2,8-Diaminononanedioic Acid CAS NO 98951-66-7 is a non-proteinogenic diaminodicarboxylic acid featuring two amino groups and two carboxylic acid functionalities on a nine-carbon chain. This unique bifunctional structure makes it a valuable intermediate for the synthesis of specialized polymers, peptide mimetics, and complex organic molecules. It is particularly relevant for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors seeking to incorporate specific diamine-diacid motifs into their products.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel active pharmaceutical ingredients (APIs), peptide analogs, and diagnostic agents.
• Polymer Chemistry: Monomer for the production of polyamides, polyimides, and other specialty polymers with tailored thermal and mechanical properties.
• Agrochemical Synthesis: Intermediate in the development of new herbicides, fungicides, and plant growth regulators.
• Biochemical Research: Used in proteomics and metabolic pathway studies as a non-standard amino acid derivative.
• Chelating Agent Precursor: Serves as a starting material for synthesizing ligands with high affinity for metal ions.
• Cross-linking Agent: Utilized in the modification of proteins, enzymes, and other biomolecules due to its two reactive amino groups.

Quality Control

Our Dl-2,8-Diaminononanedioic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, chiral analysis, and residual solvent screening to ensure it meets stringent specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

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). This compound is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture which may affect stability and handling properties.
