Hazards SummaryEmergency treatment: irritants; [HSDB] Causes convulsions in lethal-dose studies of rats (intraperitoneal); [RTECS] An irritant; [MSDSonline]
NFPA Hazard Classification
1 - Materials that, under emergency conditions, can cause significant irritation.
1 - Materials that must be preheated before ignition can occur. Materials require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur.
0 - Materials that in themselves are normally stable, even under fire conditions.

Anwendungen
Beschreibung2-Buten-1,4-diol is a palladium-containing compound that forms cross-links by reacting with an oxygen nucleophile. It reacts with nitrogen nucleophiles in the presence of hydrochloric acid to provide gamma-aminobutyric acid. This reaction mechanism is analogous to the way in which amines react with carboxylic acids to form amides. cis,trans-2-Buten-1,4-diol can be found in kinetic studies and its nmr spectra have been studied extensively.
