Additional information on PYR14-TFSI

PYR14-TFSI (CAS No: 223437-11-4) - A Comprehensive Overview

PYR14-TFSI, also known by its CAS registry number 223437-11-4, is a cutting-edge chemical compound that has garnered significant attention in the fields of electrochemistry, materials science, and energy storage. This compound, which stands for N-butyl-N-methylpyridinium bis(trifluoromethylsulfonyl)imide, is a type of ionic liquid. Ionic liquids are salts that remain in a liquid state at room temperature, making them highly versatile and valuable for various applications.

The structure of PYR14-TFSI consists of two main components: the cation (N-butyl-N-methylpyridinium) and the anion (bis(trifluoromethylsulfonyl)imide, or TFSI?). The cation is derived from pyridine, a six-membered aromatic heterocycle with nitrogen as the heteroatom. The butyl and methyl substituents on the nitrogen atom provide steric bulk and enhance the stability of the cation. The anion, on the other hand, is a highly stable and non-coordinating ion, which contributes to the overall stability and electrochemical properties of the compound.

Recent studies have highlighted the exceptional properties of PYR14-TFSI, particularly its thermal stability, electrochemical stability, and excellent ionic conductivity. These properties make it an ideal candidate for use in advanced battery systems, such as lithium-ion batteries (LIBs) and supercapacitors. In LIBs, PYR14-TFSI can act as an additive in electrolytes, enhancing the cycling performance and safety of the batteries by stabilizing the solid-electrolyte interphase (SEI) layer on the anode surface.

Moreover, PYR14-TFSI has been extensively studied for its potential in organic synthesis as a catalyst or solvent. Its ability to dissolve a wide range of organic compounds and its non-volatile nature make it particularly useful in high-temperature reactions. Recent research has also explored its application in electrochemical sensing devices, where it serves as an effective electrolyte due to its high ion mobility and wide electrochemical window.

The synthesis of PYR14-TFSI typically involves a two-step process: first, the preparation of the pyridinium salt by quaternization of pyridine with appropriate alkylating agents; second, the reaction of this salt with bis(trifluoromethylsulfonyl)imide to form the final product. This process is well-established and can be optimized to achieve high yields and purity levels.

In terms of environmental impact, PYR14-TFSI is considered relatively safe under normal handling conditions. However, like all chemicals, proper precautions must be taken during synthesis, storage, and use to minimize any potential risks. Ongoing research is also focused on understanding its biodegradation pathways and environmental fate to ensure sustainable use.

Looking ahead, PYR14-TFSI holds immense promise for future applications in energy storage technologies. With advancements in nanotechnology and materials science, researchers are exploring ways to incorporate this compound into next-generation batteries with higher energy densities and longer lifespans. Additionally, its role in green chemistry processes could further reduce reliance on traditional solvents that are harmful to the environment.

In conclusion, PYR14-TFSI (CAS No: 223437-11-4) is a versatile compound with a wide range of applications across multiple disciplines. Its unique properties make it a valuable tool in modern chemical research and industrial processes. As scientific understanding continues to evolve, so too will the potential uses of this remarkable material.
