In the realm of UV curing and photopolymerization, understanding the intrinsic properties of photoinitiators is paramount for successful formulation and application. 2-Isopropylthioxanthone, commonly abbreviated as ITX and identified by CAS number 5495-84-1, is a significant Type II photoinitiator valued for its performance characteristics. As a chemical manufacturer and supplier, we aim to provide clarity on the technical aspects of ITX that R&D scientists and procurement managers need to consider.

Key Chemical and Physical Properties of ITX

ITX, with the molecular formula C16H14OS and a molecular weight of approximately 254.35 g/mol, is typically supplied as a light yellow powder. Its physical form and appearance are important initial indicators of quality. A crucial property for its application is its solubility; ITX exhibits good solubility in most common organic solvents and UV-curable monomers and oligomers, which is essential for achieving uniform dispersion in formulations. However, it is generally insoluble in water.

The core function of ITX as a photoinitiator is dictated by its UV absorption characteristics. It possesses significant absorption bands in the UV spectrum, notably around 258 nm and 383 nm. This dual absorption capability is a key advantage, enabling efficient surface cure at shorter wavelengths and deeper penetration for through-cure in thicker or pigmented systems. This characteristic is highly valued by formulators aiming for optimal curing across diverse applications like inks, coatings, and adhesives.

Technical specifications often include a melting point range, typically between 56-72°C, and a boiling point of around 398.9°C. Purity levels, often exceeding 99.0%, are critical for ensuring consistent photoinitiation efficiency and avoiding unwanted side reactions in sensitive applications. For instance, its use as an analytical standard in food packaging research highlights the need for high purity and well-defined specifications.
