Terephthalaldehyde, 98%, Thermo Scientific Chemicals

Description

Terephthalaldehyde is used as an intermediate for the preparation of dyes and fluorescent whitening agents. It is used in the synthesis of polyimines by reacting with aliphatic diamines. It is used as a precursor for the preparation of paramagnetic microporous polymeric organic frameworks (POFs) through copolymerization with pyrrole, indole, and carbazole.

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.
