In the world of modern technology, photoinitiators play a crucial role in the development of various products ranging from coatings and inks to adhesives and dental materials. The key function of photoinitiators is to generate free radicals when exposed to light, which initiates a polymerization reaction. With the demand for high-performance photoinitiators on the rise, Ningbo Inno Pharmchem Co., Ltd., a leading manufacturer of specialty chemicals, has developed PI-369, a versatile photoinitiator suitable for various applications.

PI-369 is also known as 2-Benzyl-2-(dimethylamino)-4-morpholinyl phenylbutanone, 2-Dimethylamino-2-benzyl-1-[4-(4-morpholinyl)phenyl]-1-butanone, 2-Phenylbenzyl-2-dimethylamine-1-(4-morpholinebenzylphenyl)butanone, 2-Benzyl-2-dimethylamino-4-morpholine, 2-Benzyl-2-(dimethylamino)-1-[4-(morpholino)phenyl]-1-butanone, Photoinitiator 369, or Photoinitiator 3692-Benzyl-2-(dimethylamino)-1-[4-(4-morpholinyl)phenyl]-1-butanone. PI-369 is a highly efficient Type I photoinitiator that can be activated by UV and visible light. It exhibits excellent solubility in common solvents, making it easy to incorporate into various formulations.

One of the significant advantages of PI-369 is its broad absorption spectrum, which ranges from 300 to 420 nm. This feature makes it suitable for use in various applications, including coatings, inks, adhesives, and dental materials. Additionally, PI-369 has a low odor and low migration, making it ideal for applications that require high purity and low toxicity.

The synthetic route used to produce PI-369 by Ningbo Inno Pharmchem Co., Ltd. involves a multistep process that ensures high purity and consistency. The process begins with the reaction of 4-morpholinebenzaldehyde and benzyl bromide to produce 4-morpholinebenzyl bromide. Next, the 4-morpholinebenzyl bromide is reacted with 4-(dimethylamino)phenyl boronic acid to produce 2-(4-dimethylaminophenyl)-4-morpholinobenzyl bromide. The final step involves the reaction of 2-(4-dimethylaminophenyl)-4-morpholinobenzyl bromide and 2-butanone to produce PI-369.

The feasibility analysis of PI-369 by Ningbo Inno Pharmchem Co., Ltd. shows that it meets the requirements of various applications. In coatings, PI-369 exhibits excellent curing performance, resulting in coatings with high hardness and scratch resistance. In inks, PI-369 provides fast curing and high color development, resulting in high-quality prints. In adhesives, PI-369 offers excellent bonding strength and fast curing, resulting in strong and durable bonds. In dental materials, PI-369 exhibits excellent curing performance and low toxicity, making it suitable for use in restorative and orthodontic applications.

In conclusion, PI-369 is a highly efficient and versatile photoinitiator suitable for various applications. Its broad absorption spectrum, low odor, and low migration make it an ideal choice for applications that require high purity and low toxicity. The synthetic route used to produce PI-369 by Ningbo Inno Pharmchem Co., Ltd. ensures high purity and consistency, while the feasibility analysis shows that it meets the requirements of various applications. As a leading supplier of specialty chemicals, Ningbo Inno Pharmchem Co., Ltd. is committed to providing high-quality products and services to customers worldwide.
