Triethylenediamine (TEDA) FAQ: Specifications, Ordering and Support Questions

Triethylenediamine TEDA (CAS 280-57-9) is a versatile organic synthesis intermediate with a well-established role in polyurethane manufacturing and a range of other industrial applications. The questions below reflect what business buyers, distributors and procurement teams most commonly ask before placing an order.

1. What is triethylenediamine TEDA and what is its CAS number?

Triethylenediamine TEDA — also referred to simply as triethylenediamine or solid amine — is a bicyclic diamine compound. Its CAS registry number is 280-57-9, its molecular formula is C₆H₁₂N₂, and its molecular weight is 112.18.

2. What are the physical properties of TEDA?

At ambient conditions TEDA appears as a white or light-yellow crystal with a characteristic ammonia odor. Key physical data confirmed in product documentation:

TEDA is readily soluble in water, acetone, benzene, and ethanol. It is also soluble in straight-chain hydrocarbons such as pentane, hexane, and heptane.

3. What is triethylenediamine TEDA used for?

TEDA is classified as an organic synthesis intermediate. Documented applications include:

• Polyurethane production — catalyst in the manufacture of polyurethane foam, elastomers, plastic products, and molding processes.
• Polymer catalysis — catalyst for ethylene polymerization and ethylene oxide polymerization.
• Synthetic light-stable materials — ingredient in photostabilizer systems.
• TEDA derivatives — the compound's derivatives are used as corrosion inhibitors and emulsifiers.

4. How is TEDA packaged and stored?

The standard commercial packaging offered by Shijiazhuang Sincere Chemicals Co., Ltd. is a 25 kg cardboard barrel. Buyers requiring alternative quantities or packing formats should raise this during the inquiry stage, as the published specification documents the 25 kg barrel as the standard unit.

5. What purity grade does Shijiazhuang Sincere Chemicals Co., Ltd. supply?

The confirmed product specification lists a minimum content of ≥ 99.5 %, qualifying it as a high-purity technical grade suitable for demanding catalytic and synthesis applications. For quality-assurance documentation requirements, contact the sales team when submitting your inquiry.
