For chemists and R&D professionals, selecting the correct chemical specifications for intermediates like 5-(2-Bromoethyl)-2,3-dihydrobenzofuran (CAS 127264-14-6) is fundamental to the success of their synthetic projects. As a key player in pharmaceutical synthesis and organic chemistry, understanding the detailed specifications of this compound ensures optimal performance and reliable outcomes. This guide outlines what buyers should look for when purchasing this intermediate, with a focus on sourcing from reputable manufacturers.

The primary specification to scrutinize is purity. High-purity 5-(2-Bromoethyl)-2,3-dihydrobenzofuran, typically specified as ≥98% as determined by GC or HPLC, is crucial. Impurities can significantly affect reaction yields, introduce unwanted byproducts, and complicate downstream purification processes. Therefore, always request the Certificate of Analysis (COA) from your supplier to verify the purity and the analytical methods used. Other important specifications might include moisture content and the absence of specific critical impurities relevant to your application.

The physical appearance is another key indicator. The compound is generally described as a white to off-white crystalline powder. While seemingly minor, consistency in appearance can reflect a well-controlled manufacturing process. Knowing the molecular formula (C10H11BrO) and molecular weight (227.1) is standard for chemical intermediates and should be readily available from any reputable supplier.

When planning to buy this compound, consider the storage conditions recommended by the manufacturer. For many intermediates like this, cool storage conditions are often advised to maintain stability. Suppliers should also provide clear packaging information, ensuring the product is protected during transit and upon arrival.

For procurement professionals and chemists, partnering with a manufacturer that prioritizes these specifications is paramount. Sourcing from established suppliers in China, who are often equipped with large-scale production capabilities and robust quality control, can provide a reliable source for 5-(2-Bromoethyl)-2,3-dihydrobenzofuran. By diligently reviewing these specifications, you can make informed decisions that support the efficiency and success of your chemical synthesis endeavors.
