Product Name:TRANS-1,4-CYCLOHEXANE DIISOCYANATE
English Name:TRANS-1,4-CYCLOHEXANE DIISOCYANATE
CAS No.:7517-76-2
Aliases:trans-1,4-Cyclohexylene diisocyanate, CHDI, trans-1,4-Cyclohexyl isocyanate
Molecular Formula:C8H10N2O2
Physical Properties:Colorless to light yellow transparent liquid with an irritating odor. Molecular weight 166.18, density approximately 1.07 g/cm³, boiling point approximately 110-112°C (5 mmHg), flash point above 110°C. Soluble in organic solvents such as toluene, ethyl acetate, and dimethylformamide; reacts with water or alcohols releasing carbon dioxide.
