DISPERSE RED 19 Chemical Properties,Uses,Production

Chemical Properties

dark purple to dark red-brown crystalline powder

Uses

DR19 can be used as red side groups in an NLO polyester for potential application in optical switching devices. It can also be bonded with polyurethane to form stable films, which may be used in the fabrication of analog systems.

Preparation

4-Nitrobenzenamine diazo, and N,N-dihydroxyethylaniline?coupling.

General Description

Disperse Red 19 (DR19) is widely used as a non-linear optical (NLO) dye with two hydroxyl (OH) groups, which can covalently connect with the base polymer. It can be linked as a side chain group that provides thermal and photo stability to the polymeric unit.
