CAS 112-24-3 corresponds to Triethylenetetramine (TETA or Trien), which is a strong alkaline polyamine compound with the molecular formula C ₆ H ₁ N ₄ and a molecular weight of 146.23. It is a light yellow to colorless viscous liquid at room temperature and is mainly used as a curing agent for epoxy resins, a metal chelating agent, and a chemical synthesis intermediate.

Core physicochemical properties
-Appearance: Light yellow or colorless viscous liquid (pure product almost colorless), with ammonia odor
-Melting point/freezing point: 12 ℃; Boiling point: 266-267 ℃
-Density: 0.9818 g/cm ³ (20/20 ℃); Refractive index: 1.4971
-Solubility: miscible with water and ethanol, slightly soluble in ether
-Hazard: Flash point 143 ℃, self ignition point 338 ℃, classified as corrosive (UN 2259, Class 8), strongly alkaline and allergenic

main purpose
1. Resin curing: Epoxy resin room temperature/heating curing agent (core application)
2. Industrial additives: rubber accelerators, lubricant additives, fuel oil detergents and dispersants
3. Chemical synthesis: polyamide resin, ion exchange resin, surfactants, and dye intermediates
4. Special functions: metal chelating agent (cyanide free electroplating), gas purifying agent, fabric finishing agent

Safety and Storage
-Health hazards: Highly corrosive, contact can cause skin/eye burns, respiratory irritation, and allergies; Long term exposure affects the blood system
-Emergency measures: In case of skin contact, immediately rinse with plenty of water and apply boric acid ointment; If ingested or inhaled, seek medical attention immediately
-Storage requirements: Sealed, dark, moisture-proof, away from oxidants and acids, stored in a cool and ventilated place

This substance is a byproduct of the ethylene diamine series produced by the dichloroethane amination method, and industrial grade products often contain small amounts of homologues (such as diethylenetriamine and tetraethylenepentamine).
