Description

Propane-1,3-Diamine CAS NO 68333-86-8 is a versatile aliphatic diamine, also known as 1,3-diaminopropane, characterized by its two primary amine groups separated by a three-carbon chain. This bifunctional structure makes it a valuable building block in organic synthesis, particularly for creating polymers, chelating agents, and pharmaceutical intermediates. It is essential for manufacturers and R&D facilities in the agrochemical, pharmaceutical, polymer, and specialty chemical industries seeking a reliable, high-purity diamine for complex synthesis.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs requiring diaminoalkane backbones.
• Polymer & Resin Production: Serves as a curing agent for epoxy resins and a monomer for producing polyamides, polyurethanes, and other specialty polymers.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators where its diamine functionality is incorporated into the final molecule.
• Chelating Agent Precursor: A starting material for synthesizing ligands and chelating agents used in water treatment, metal extraction, and catalysis.
• Corrosion Inhibitor Formulation: Component in formulations designed to protect metals in industrial cooling systems and other applications.
• Organic Synthesis Reagent: Employed in various organic reactions, including nucleophilic substitution and as a linker molecule in medicinal chemistry.

Quality Control

Our Propane-1,3-Diamine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets the high standards required for industrial and research applications. A Certificate of Analysis (COA) detailing purity and specific test results is provided with every shipment to guarantee supply reliability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, containers should be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Recommended storage temperature is 15-25°C.
