Description

n-(3-Aminopropyl)-4-Aminobutanal is a specialized bifunctional aliphatic amine-aldehyde intermediate. This compound is valued for its unique reactivity, offering both a primary amine and an aldehyde group for sequential or simultaneous chemical modifications. It serves as a critical building block in advanced organic synthesis, particularly for the creation of complex molecular architectures. Key industries that utilize this intermediate include pharmaceutical research, agrochemical development, and the production of specialty polymers and cross-linking agents.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring specific amine-aldehyde conjugation.
• Cross-linking Agent: Functions as a versatile linker in polymer chemistry for creating hydrogels, resins, and other cross-linked materials.
• Bioconjugation Reagent: Employed in biochemical research for labeling proteins, antibodies, or other biomolecules via Schiff base formation.
• Agrochemical Synthesis: Serves as a precursor in the development of novel herbicides, fungicides, and plant growth regulators.
• Chelating Ligand Precursor: Used to synthesize polyamine ligands for metal complexation and catalysis.
• Surface Modification: Applied for functionalizing material surfaces (e.g., silica, polymers) to introduce amine groups for further coupling.

Quality Control

Our n-(3-Aminopropyl)-4-Aminobutanal is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity assessment and functional group verification, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed specifications are provided for every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. For long-term stability, storage at 2-8°C is advised. Keep the container tightly sealed when not in use to minimize exposure to air and moisture.
