The intricate chemistry behind UV curing relies heavily on the performance of photoinitiators – molecules that transform light energy into the chemical reactions needed for polymerization. For scientists and procurement professionals working with UV-curable materials, a thorough understanding of these key components is crucial for successful formulation and efficient production. This deep dive focuses on N, N′,N″-Tris[4-[(1,4-dimethylpentyl)amino]phenyl]-1,3,5-triazine-2,4,6-triamine, identified by its CAS number 121246-28-4, a prominent photoinitiator manufactured and supplied by NINGBO INNO PHARMCHEM CO.,LTD., a leading specialty chemical company in China.

CAS 121246-28-4 is a Type I photoinitiator, meaning it undergoes unimolecular bond cleavage upon absorption of UV light to directly generate free radicals. This characteristic is vital for applications requiring rapid and efficient polymerization initiation. The molecular structure, featuring a central triazine ring with three pendant phenylamino groups, each further substituted with a 1,4-dimethylpentyl chain, is engineered for optimal UV absorption and radical generation efficiency. The presence of the bulky alkyl chains influences its solubility and compatibility within various resin systems.

The physical form of this photoinitiator is a fine red powder, offering a purity level of 99%. This high purity is a critical factor for formulators, ensuring predictable reactivity and minimizing the introduction of unwanted side reactions or impurities into the final product. For R&D scientists evaluating photoinitiators, this level of quality from manufacturers like NINGBO INNO PHARMCHEM is essential for reliable experimental results and scalable production. Procurement managers will find that sourcing high-purity materials directly from manufacturers often provides better value and a more secure supply.

The UV absorption spectrum of CAS 121246-28-4 is tailored to complement common UV light sources, such as medium-pressure mercury lamps, making it suitable for a broad range of industrial UV curing applications. Its effectiveness in pigmented systems is a particularly noteworthy advantage, as many traditional photoinitiators struggle to initiate cure through colored formulations. The red powder nature of this compound, while imparting color, can be advantageous in certain ink and coating formulations, or it can be used in conjunction with other photoinitiators to optimize curing across the entire UV spectrum.

When considering the purchase of CAS 121246-28-4, understanding its role within a specific formulation is key. Its high reactivity contributes to fast cure speeds, which is beneficial for high-throughput manufacturing. However, formulators must also consider potential yellowing, migration, and odor, which are influenced by the photoinitiator and other formulation components.
