Product introduction

Introduction and application of 4-(Methylamino)benzaldehyde | CAS No.556-21-8

4-(Methylamino)benzaldehyde (4-MABA) is a positron-emitting substance that has been used in positron emission tomography (PET) imaging. 4-MABA is synthesized by hydrolysis of copper(II) complexes with 4-aminobenzaldehyde. It can also be synthesized by reacting copper(II) salts with 4-methylaniline. This substance is stable in aqueous solution, but hydrolyzes readily in the presence of water to form copper(I). The most likely electron acceptor for this reaction is oxygen, which leads to the formation of a stable complex. For diagnostic purposes, radiolabeled 4-MABA can be used as an indicator for positron emission from various tissues and organs.

Synonyms:
