Chloroformamidine hydrochloride Usage And Synthesis

Chemical Properties

White crystalline powder

Reactions

In efforts to optimize a manufacturing process for an internal development compound, a clean, efficient approach to guanidine synthesis using chloroformamidine hydrochloride was identified. The successful application of this chemistry to a variety of pyridines, anilines, and heterocyclic compounds highlights its use as an improved, alternative guanylation method for this often challenging set of aromatic amines.[1]

Materials Uses

An interfacial molecular linker, chloroformamidine hydrochloride (CFA), is introduced to modify the properties of electron transport layers (ETLs) and modulate the interaction between the ETL and perovskite (PVK) layer via coordination/electrostatic coupling. It is found that the CFA molecular linker can passivate the oxygen vacancies/interfacial defects of SnO2 and construct an improved energetic alignment between the ETL and PVK layer. Moreover, unencapsulated PSCs based on CFA-modified SnO2 (CFA@SnO2) ETLs show enhanced thermal and moisture stability compared with PSCs without CFA modification.[2]
