For procurement managers and R&D scientists in the chemical industry, understanding where and how to source essential raw materials like 2-hydroxy-2-methylpropiophenone (Photoinitiator 1173, CAS 7473-98-5) is critical. This article serves as a guide to help B2B buyers navigate the process of acquiring this vital photoinitiator, focusing on specifications, applications, and reliable sourcing from China.

Photoinitiator 1173 is a key ingredient for UV-curable systems, widely used in inks, coatings, and adhesives. When purchasing, it’s essential to verify the product's specifications to ensure it meets your formulation requirements. Key parameters include appearance (typically a transparent yellow liquid), assay (often ≥99.0%), and molecular formula (C10H12O2). These details guarantee the efficacy of the photoinitiator in promoting rapid UV-induced polymerization.

The primary applications of 2-hydroxy-2-methylpropiophenone are in industries demanding efficient and precise curing. This includes UV painting, where it enables fast drying and durable finishes, and UV inks, where it contributes to vibrant, quick-setting prints. Furthermore, its low yellowing properties make it ideal for wood coatings and furniture paints, protecting the aesthetic integrity of the final product.

When looking to buy Photoinitiator 1173, especially in bulk quantities, China has emerged as a significant manufacturing hub. Identifying reliable manufacturers and suppliers is paramount. Buyers should look for suppliers who can provide consistent quality, competitive pricing, and robust technical support. Engaging with manufacturers that offer detailed product data sheets (TDS) and safety data sheets (SDS) is also a best practice.

For those seeking to obtain a quotation, direct contact with established chemical suppliers is the most effective route. Inquiries should ideally specify the required purity, quantity, and intended application to receive the most accurate pricing and supply chain information. Understanding the global supply dynamics and the competitive landscape can also aid in negotiation and securing favorable purchase terms.

In conclusion, sourcing 2-hydroxy-2-methylpropiophenone requires careful attention to product specifications and supplier reliability. By focusing on high-purity materials and partnering with reputable Chinese manufacturers, businesses can ensure a stable supply of this critical photoinitiator, thereby optimizing their UV curing processes and product quality.
