EC number: 222-852-4
CAS number: 3634-83-1
The substance is a colourless liquid.
As the substance is a diisocyanate, it reacts with water. Isocyanates
hydrolyze readily in water to yield a carbamic acid, which
decarboxylates to produce CO2 and an amine; the latter can immediately react
with more isocyanate to yield a disubstituted urea. The hydrolysis rate
increases with electron-withdrawing substituents. Steric hindrance also
influences hydrolysis rate. Even at low pHs, hydrolysis Half-Life < 10
minutes (25 deg C) have been found for isocyanates.
