1 3-Propanediamine CAS 109-76-2

1. 1,3-Propanediamine is primarily used as a key building block in polymer production for synthesizing polyamides, polyurethanes, and as a curing agent for epoxy resins .
2. 1 3-Propanediamine CAS 109-76-2 serves as an intermediate in pharmaceutical development for drugs targeting neurological disorders like Alzheimer's disease and for thrombosis inhibitors .
3. Applications of 1,3-Propanediamine also include formulating corrosion inhibitors for industrial pipelines, acting as a linker in bioconjugation for drug delivery systems, and preparing agrochemicals and surfactants .

1. Store 1,3-Propanediamine in a tightly sealed container under inert gas (e.g., nitrogen) in a cool, dry, well-ventilated place, protected from moisture and light; recommended storage is below 15°C or at room temperature in a cool, dark area .
2. Keep 1,3-Propanediamine away from heat, sparks, open flames, strong oxidizing agents, and acids due to its flammability and incompatibility .
3. Always 1 3-Propanediamine CAS 109-76-2 use appropriate personal protective equipment (PPE) including chemical-resistant gloves, safety goggles, protective clothing, and explosion-proof ventilation; avoid breathing vapors and ensure operations are in a fume hood .

1. Immediately evacuate the area, eliminate all ignition sources, and contain the 1,3-Propanediamine spill with inert, non-combustible absorbent material (e.g., sand); prevent entry into drains or waterways .
2. Carefully collect 1 3-Propanediamine CAS 109-76-2 into a sealed, labeled chemical waste container for proper disposal according to hazardous material regulations .
3. Personnel must wear suitable PPE including self-contained breathing apparatus (SCBA) during cleanup; for large spills, use dikes to contain and then transfer to containers for recovery or disposal .

1. 1,3-Propanediamine is classified as a flammable liquid and vapor (H226) and is corrosive, causing severe skin burns and serious eye damage (H314); 1 3-Propanediamine CAS 109-76-2 is harmful if swallowed, inhaled, or in contact with skin (H302+H312+H332) .
2. 1,3-Propanediamine has an acute oral LD50 of 350 mg/kg in rats and dermal LD50 of 200 mg/kg in rabbits; thermal decomposition produces toxic fumes including nitrogen oxides, carbon monoxide, and carbon dioxide .
3. Always consult the specific Safety Data Sheet (SDS) for 1,3-Propanediamine for complete hazard information, first-aid procedures (do NOT induce vomiting if swallowed), and handling instructions; UN classification is UN2734, Class 8/3, PG II .
