trans-1,4-Cyclohexane diisocyanate, 97%

Description

CAS: 7517-76-2 | C8H10N2O2 | 166.18 g/mol

Mixed aromatic/alicyclic polyimides were prepared by polycondensation reactions of trans-1,4-cyclohexane diisocyanate CHDI with PMDA, BTDA, and 6FDA. The intermediate reactivity observed for CHDI, allows preparation of polyurethanes.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
