For professionals in research and development, as well as procurement specialists in the chemical industry, understanding the nuances of specific compounds is vital for successful project execution. 1,4-Diethynylbenzene (CAS 935-14-8) is one such chemical that demands careful attention regarding its purity, price, and procurement methods. This article aims to shed light on these aspects, particularly for those looking to source this compound for advanced applications like COF synthesis and polymer research.

The purity of 1,4-Diethynylbenzene is arguably its most critical attribute. Typically available in grades ranging from 95% to over 98.0% (GC), the specific purity required heavily depends on the intended application. For cutting-edge research in materials science, such as the synthesis of Covalent Organic Frameworks (COFs) or the development of high-performance polymers, a higher purity grade is almost always preferred. Impurities can act as chain terminators in polymerization, interfere with self-assembly processes in framework construction, or lead to unintended side reactions, compromising the integrity and performance of the final material. Therefore, when inquiring about price, it is essential to specify the desired purity level.

The price of 1,4-Diethynylbenzene can fluctuate based on several factors, including purity, order quantity, and the supplier. Generally, higher purity grades command higher prices. Similarly, purchasing in bulk—kilograms or larger quantities—will typically result in a lower price per kilogram compared to small laboratory-scale amounts. For industrial users, exploring wholesale options from manufacturers, especially those based in China, often presents the most cost-effective solution. Manufacturers typically offer the most competitive pricing structures due to their direct control over the production process.

Procurement of 1,4-Diethynylbenzene involves selecting a reliable source. When looking to buy this compound, consider partnering with established manufacturers and suppliers who can guarantee quality and consistency. China has a robust chemical manufacturing sector, and many companies there specialize in producing organic intermediates like 1,4-Diethynylbenzene. When you request a quote, it's advisable to solicit proposals from several reputable China-based manufacturers to compare pricing, lead times, and their ability to meet your specific quality requirements. Ensure they can provide a detailed Certificate of Analysis (CoA) with each batch.

Furthermore, understanding the specific needs of your application is key to efficient procurement. For instance, if you are using 1,4-Diethynylbenzene as a monomer for COF synthesis, you might have specific requirements for particle size or morphology. Communicating these needs clearly to your supplier will help them provide the most suitable product. Always verify the CAS number (935-14-8) and any associated synonyms to ensure you are procuring the correct chemical.

In conclusion, a thorough understanding of 1,4-Diethynylbenzene's purity requirements, the factors influencing its price, and a strategic approach to procurement—often involving direct sourcing from manufacturers in China—will enable you to secure this vital building block effectively for your advanced material research and production needs.
