1:8-Diaza Bicyclo Undecene for Synthesis (Dbu) | 6674-22-2:

1,4-Diazabicyclo[2.2.2]octane, also known as TED or Triethylenediamine, is a white to light yellow crystalline powder used primarily as a curing catalyst in polymer and polyurethane chemistry. Known for its high purity (minimum 99.0% GC assay) and catalytic efficiency, TED plays a critical role in industrial applications requiring precise chemical performance.

Key Features:

• Appearance: White to light yellow powder or crystal

• Purity (GC Assay): ≥ 99.0%

• Melting Point: 156–159 °C

• Solubility: Soluble in water, acetone, benzene, ethanol, and methyl ethyl ketone

• Stability: Chemically stable under recommended storage conditions

• Synonyms: TED, Triethylenediamine

Applications:

• Catalyst in the production of polyurethane foams and resins

• Used in curing systems for epoxy resins and industrial coatings

• Serves as a chemical intermediate in pharmaceutical and specialty chemical synthesis

• Commonly utilized in plastics, adhesives, and elastomers manufacturing

Safety & Handling:

Hazard Statements:

• Flammable solid

• Harmful if swallowed

• May cause respiratory irritation

• Causes mild skin and eye irritation

Precautionary Measures:

• Keep away from heat, sparks, and open flames – No smoking

• Ground/bond containers and use explosion-proof equipment

• Use only non-sparking tools

• Wear protective gloves, clothing, and eye/face protection

• Wash your hands thoroughly after handling

• Do not eat, drink, or smoke when handling this chemical

First Aid Measures:

• Eye Contact: Rinse cautiously with water; remove contact lenses if present and easy

• Skin Contact: Rinse with water/shower; remove contaminated clothing

• Ingestion: Rinse mouth; do not induce vomiting

• Inhalation: Move to fresh air and seek medical attention if symptoms persist

Disposal Guidelines:

• For small quantities: allow to evaporate in a well-ventilated area

• For large volumes (>500 ml): incinerate in a chemical incinerator with scrubber

• If incineration is not possible, collect in solvent waste drums for disposal by a certified hazardous waste company
