In the competitive landscape of chemical procurement, obtaining the right intermediates at the right price, with guaranteed quality, is paramount. Biphenyl-4,4'-dicarboxylic Acid, identified by CAS Number 787-70-2, is a key organic intermediate that demands careful sourcing consideration by chemists and procurement managers alike.

Biphenyl-4,4'-dicarboxylic Acid, a white crystalline powder (C14H10O4, MW 242.23 g/mol), features a robust biphenyl core with two reactive carboxylic acid groups. This structural motif makes it a highly sought-after building block for a range of advanced materials, from high-performance polymers to components in organic electronics. When it comes to purchasing, the purity of this intermediate is often the most critical specification. Most applications require a minimum purity of 99%, as even slight impurities can significantly impact the properties of the final product, be it a polymer or an electronic device.

The price of Biphenyl-4,4'-dicarboxylic Acid is influenced by several factors, including market demand, raw material costs, production scale, and purity levels. For procurement professionals aiming to buy this compound, understanding these variables is key to negotiating favorable terms. Manufacturers based in regions with efficient chemical production infrastructure, such as China, often provide competitive pricing. For instance, NINGBO INNO PHARMCHEM CO.,LTD. is a prominent supplier that offers this chemical, balancing quality with cost-effectiveness, especially for bulk purchases.

When making a purchase decision, it is imperative to engage with suppliers who provide transparent documentation. A Certificate of Analysis (CoA) for each batch is essential, detailing the purity, analytical methods used, and other critical specifications. Beyond the CoA, consider the supplier's reliability in terms of consistent stock availability and delivery timelines. A responsive supplier who can provide samples for initial testing and offer technical support further enhances the procurement process.

The applications of Biphenyl-4,4'-dicarboxylic Acid are diverse and impactful. In polymer science, it acts as a monomer in the creation of specialty polyesters, polyamides, and polyimides known for their exceptional thermal stability and mechanical strength, vital for demanding industries like aerospace and automotive. In the electronics sector, it serves as a precursor for organic semiconductors used in OLEDs and OFETs, where precise molecular design dictates performance. For research and development purposes, buying smaller quantities for experimental work is also common, necessitating suppliers who cater to diverse order sizes.

In conclusion, Biphenyl-4,4'-dicarboxylic Acid (CAS: 787-70-2) remains a cornerstone intermediate for advanced material synthesis. Buyers seeking to purchase this compound should prioritize high purity, investigate pricing from reputable manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., and ensure thorough documentation and reliable logistics. A strategic approach to procurement guarantees that this versatile molecule can effectively drive innovation in polymer science and organic electronics.
