For businesses involved in coatings, inks, adhesives, and other UV-curable applications, selecting the right photoinitiator is paramount to achieving desired curing speeds, film properties, and overall product performance. Among the vast array of available options, 4-Chlorobenzophenone (CAS 134-85-0) stands out as a highly effective Type II free radical photoinitiator, favored by many manufacturers for its robust capabilities.

As a leading supplier of specialty chemicals, we understand the challenges B2B procurement managers and R&D scientists face. This guide aims to shed light on why 4-Chlorobenzophenone is a compelling choice and what to consider when buying this essential component. Its primary advantage lies in its ability to initiate radical polymerization when exposed to UV light, particularly when used in conjunction with co-initiators like tertiary amines. This synergy allows for rapid curing, even in thicker films or pigmented systems, which is critical for efficient production lines.

One of the key benefits of 4-Chlorobenzophenone is its strong anti-yellowing ability. In applications where color stability is crucial, such as clear coats or white inks, this property ensures the longevity and aesthetic appeal of the final product. Unlike some other photoinitiators that can impart a yellowish tint over time, 4-Chlorobenzophenone maintains clarity and brightness, making it a preferred choice for premium formulations.

Beyond its role in UV curing, 4-Chlorobenzophenone also serves as a vital intermediate in the synthesis of pharmaceuticals and pesticides. Its chemical structure makes it a valuable building block for creating complex molecules used in medicines, such as antitussives, and in the agricultural sector. For companies seeking to purchase chemical intermediates, sourcing a high-purity grade of 4-Chlorobenzophenone from a reliable manufacturer in China can offer significant cost advantages and supply chain stability.

When evaluating potential suppliers, factors such as purity (typically ≥99%), consistent batch-to-batch quality, packaging options (e.g., 20kg cartons or drums), and adherence to safety standards are crucial. Understanding the material's physical properties, like its white crystalline powder appearance and melting range of 75-77°C, is also important for proper handling and storage. We, as an experienced manufacturer and supplier, ensure that our 4-Chlorobenzophenone meets these stringent requirements, providing you with a product that delivers predictable and excellent results.
