For research and development chemists, the journey to discovering and synthesizing new molecules is often paved with the careful selection of chemical building blocks. Among these, 2-(2-Bromoethoxy)tetrahydro-2H-pyran, with its CAS number 17739-45-6, has emerged as a valuable intermediate. Understanding its properties and how to procure it effectively is crucial for efficient and successful experimental work.

The chemical structure of 2-(2-Bromoethoxy)tetrahydro-2H-pyran offers distinct advantages for synthetic chemists. Its molecular formula, C7H13BrO2, and molecular weight of 209.08 indicate a relatively small, manageable molecule. The presence of the bromoethoxy group provides a reactive handle for nucleophilic displacement reactions, allowing for the introduction of various functionalities. Concurrently, the tetrahydropyran ring offers a stable cyclic ether system, which can influence stereochemistry and solubility, or serve as a protecting group.

When R&D chemists need to buy 2-(2-Bromoethoxy)tetrahydro-2H-pyran, the primary concern is purity. A high level of purity, typically specified as 95% or 99% minimum, is essential to ensure that reactions proceed as expected and that the desired product can be isolated with minimal contamination. Impurities can lead to side reactions, reduced yields, and complicate analytical characterization. Therefore, sourcing from suppliers who provide detailed purity specifications and reliable Certificates of Analysis is paramount.

The global supply chain for chemical reagents has become increasingly interconnected. Many R&D chemists rely on international manufacturers and suppliers, particularly from regions like China, for cost-effective and high-quality intermediates. For CAS 17739-45-6, procuring from a reputable Chinese manufacturer can offer significant advantages in terms of price and availability, especially for larger quantities needed for scale-up studies or library synthesis. These suppliers often have extensive experience in producing and exporting such compounds worldwide.

Key considerations when engaging with a supplier include their ability to provide prompt quotations, their lead times for delivery, and their customer service responsiveness. For R&D purposes, having access to small to medium quantities of the compound is often necessary. Many suppliers cater to this need by offering various packaging sizes. Furthermore, the option to request a sample is invaluable for chemists to independently verify the quality before committing to a larger purchase. Understanding the physical properties, such as its appearance as a colorless liquid, and recommended storage conditions are also vital for proper laboratory handling.

In essence, for R&D chemists, procuring 2-(2-Bromoethoxy)tetrahydro-2H-pyran (CAS 17739-45-6) involves a strategic evaluation of product specifications, purity requirements, and supplier reliability. By leveraging the capabilities of global manufacturers and focusing on quality assurance, chemists can ensure they have the essential building blocks needed to drive their innovative research forward.
