For professionals in the chemical and pharmaceutical industries, a deep understanding of product specifications is fundamental to making informed purchasing decisions. Thioxanthone (CAS: 492-22-8) is a compound where precise specifications, particularly regarding purity, directly correlate with its performance in diverse applications, ranging from pharmaceutical synthesis to its role as a photoinitiator.

When a procurement specialist or a research scientist decides to buy Thioxanthone, they typically look for key information such as its CAS number (492-22-8), molecular formula (C13H8OS), and molecular weight (212.27). Equally important are its physical characteristics: Thioxanthone is generally supplied as a yellow crystalline powder. Beyond these basic identifiers, the purity level is paramount. Reputable manufacturers often specify a minimum purity of ≥97% (HPLC), which is critical for ensuring predictable and reliable outcomes in sensitive applications.

The applications of Thioxanthone are varied, underscoring the need for tailored specifications. As a pharmaceutical intermediate, high purity is non-negotiable to ensure the safety and efficacy of the final drug product. In its capacity as a Type II photoinitiator, Thioxanthone's absorptive properties in the near-UV spectrum are crucial. Understanding its spectral data, such as absorption maxima, can help formulators optimize their UV curing systems for applications in printing inks, coatings, and adhesives. The efficiency of polymerization is directly linked to the quality of the photoinitiator.

When evaluating a Thioxanthone supplier, it is advisable to request detailed Certificates of Analysis (CoA) that confirm purity and other critical parameters. This documentation provides tangible proof of the product's quality. For companies seeking cost-effectiveness without compromising quality, exploring options from manufacturers in China, such as NINGBO INNO PHARMCHEM CO.,LTD., can be beneficial. We prioritize transparency and provide comprehensive product data to assist our clients in their selection process, ensuring they receive Thioxanthone that perfectly matches their application requirements.
