When you're deep in the world of chemical synthesis, sometimes a specific product number can feel like a secret handshake. For those looking for 4-fluorophenylboronic acid, and specifically a TCI (Tokyo Chemical Industry) product number, it’s a bit like asking for a specific key in a vast locksmith's shop. While the reference material doesn't directly give a TCI product number, it does offer a wealth of information about this fascinating compound.
Let's start with the basics. 4-Fluorophenylboronic acid, with the CAS number 1765-93-1, is a white to beige crystalline powder. It's not just a pretty face, though; its chemical formula, C6H6BFO2, and molecular weight of 139.92 hint at its structural significance. You might notice it has a melting point around 262-265°C, and while it's only slightly soluble in water, it plays a crucial role in various chemical reactions.
What makes this compound so interesting? Well, it's a versatile player in organic synthesis and a key intermediate in pharmaceutical development. Think of it as a building block. It's used in reactions like the Suzuki coupling, a powerful tool for creating carbon-carbon bonds, and in palladium-catalyzed cyanation. It's also instrumental in synthesizing complex molecules, including certain drug precursors, like an important intermediate for the synthesis of empagliflozin, a medication used to treat type 2 diabetes. Beyond pharmaceuticals, it finds its way into creating fluorescent materials and other specialized organic compounds.
Digging a little deeper, the reference material lists several upstream raw materials that lead to its creation, such as 4-fluorophenyl triflate and 1-chloro-4-fluorobenzene. And the downstream products? They're equally diverse, ranging from aldehydes and ketones to more complex heterocyclic compounds. This interconnectedness highlights how a single chemical can be a linchpin in a much larger chemical ecosystem.
Now, about those product numbers and suppliers. The reference does list specific product codes like 'f0361' for a 5g pack and 'xw17659313' for a 100g pack, along with their prices. It also points to a global network of 675 suppliers, with many prominent ones based in China, like Shanghai Arbor Chemical Technology Co., Ltd., Anhui Zhishan New Material Co., Ltd., and Beijing Bailingwei Technology Co., Ltd. For those specifically seeking TCI products, a quick search on their official website or through their distributors would be the most direct route to finding their specific product identifier for 4-fluorophenylboronic acid.
Safety is always paramount, and 4-fluorophenylboronic acid is flagged with hazard symbols indicating it's an irritant (skin, eyes, and respiratory tract) and harmful if swallowed. Standard safety precautions, like wearing protective gear and ensuring good ventilation, are essential when handling it.
Ultimately, while a specific TCI product number might be the immediate goal, understanding the broader context—its properties, applications, and the network of suppliers—provides a much richer appreciation for this important chemical intermediate.
