Benzeneacetonitrile, 2-methyl-α-[2-[[(propylsulfonyl)oxy]imino]-3(2H)-thienylidene]-

Light yellow to yellow brown solid.

Benzeneacetonitrile, 2-methyl-α-[2-[[(propylsulfonyl)oxy]imino]-3(2H)-thienylidene]-, also known as Acid-producing agent PAG 103, can be used in OLED and other electronic fields. Moreover, it could be added to photoresists to increase their sensitivity to ultraviolet (UV) light. When the resist is exposed to UV light, PAG 103 generates acid, initiating chemical reactions within the photoresist. This acid acts as a catalyst within the photoresist, promoting reactions such as crosslinking, polymerization, or degradation.
