7517-76-2 Cyclohexane, 1,4-diisocyanato-, trans- Isocyanic acid, 1,4-cyclohexylene ester, trans- (8CI) H-19218 trans-1,4-Cyclohexanediisocyanate trans-1,4-Cyclohexyleneisocyanate trans-1,4-Diisocyanatocyclohexane (CAS 7517-76-2) is a high-purity analytical reference standard with the molecular formula C8H10N2O2 and a molecular weight of 166.18 g/mol.

7517-76-2 Cyclohexane, 1,4-diisocyanato-, trans- Isocyanic acid, 1,4-cyclohexylene ester, trans- (8CI) H-19218 trans-1,4-Cyclohexanediisocyanate trans-1,4-Cyclohexyleneisocyanate trans-1,4-Diisocyanatocyclohexane (C8H10N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 7517-76-2 Cyclohexane, 1,4-diisocyanato-, trans- Isocyanic acid, 1,4-cyclohexylene ester, trans- (8CI) H-19218 trans-1,4-Cyclohexanediisocyanate trans-1,4-Cyclohexyleneisocyanate trans-1,4-Diisocyanatocyclohexane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
