AJ19R479CQ 629-20-9 Cyclooctatetraene 1,3,5,7-Cyclooctatetraene (8)Annulene EINECS 211-080-3 NSC 5093 UNII-AJ19R479CQ Cyclooctatetraene [UN2358] [Flammable liquid] UN2358 CAS 629-20-9 chemical structure

Description

Owing to an aromatic ring system, AJ19R479CQ 629-20-9 Cyclooctatetraene 1,3,5,7-Cyclooctatetraene (8)Annulene EINECS 211-080-3 NSC 5093 UNII-AJ19R479CQ Cyclooctatetraene [UN2358] [Flammable liquid] UN2358 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 104.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
