Bis[2,6-difluoro-3-(1H-pyrrol-1-yl)phenyl]titanocene

Bis[2,6-difluoro-3-(1H-pyrrol-1-yl)phenyl]titanocene (CAS 125051-32-3, EC 412-000-1) is a titanocene-based photoinitiator commercially known as Irgacure 784, LS 784, PI 784, IC 784, and APi-784. It belongs to the organotitanium catalyst family and initiates radical polymerization upon exposure to visible light, particularly in the 400-550 nm range.

In UV/visible-light-curable coatings and adhesives, this compound generates reactive radicals under visible light irradiation, enabling cure initiation through pigmented or thick film systems where UV penetration is limited. It is also employed in photopolymerizable sealants and elastomer formulations where controlled, light-triggered crosslinking is required.

This material is supplied as a powder and is subject to REACH registration requirements within the European Economic Area. Procurement professionals should confirm lot-specific purity documentation and SDS compliance prior to ordering. Standard packaging formats vary by supplier; consult your account manager for available quantities.
