For chemists engaged in organic synthesis, having a reliable arsenal of reactive intermediates is crucial for innovation and efficiency. 6-Bromohexanoyl Chloride (CAS 22809-37-6) is one such compound, a potent acyl chloride that offers a unique combination of reactivity and a functionalized alkyl chain. Its utility spans from basic research to the development of complex molecules used in pharmaceuticals, agrochemicals, and material science. Understanding how to effectively buy 6-bromohexanoyl chloride and employ it in your laboratory is key to unlocking its full potential.

Understanding the Reactivity of 6-Bromohexanoyl Chloride

As an acyl chloride, the carbonyl carbon in 6-Bromohexanoyl Chloride is highly electrophilic, making it susceptible to nucleophilic attack. This property allows it to readily participate in acylation reactions, forming ester, amide, or anhydride linkages with alcohols, amines, and carboxylic acids, respectively. The presence of the terminal bromine atom on the hexanoyl chain provides a secondary reactive handle. This bromine can be displaced through nucleophilic substitution reactions, enabling further functionalization or the creation of carbon-carbon bonds via organometallic reagents.

The compound’s physical properties, such as its liquid form at room temperature (colorless to light yellow) and its density of approximately 1.395 g/mL, are important considerations for laboratory handling and reaction setup. When you plan to purchase 6-bromohexanoyl chloride, ensure you have appropriate safety measures in place, as acyl chlorides are typically reactive and moisture-sensitive.

Key Applications in Organic Synthesis

  • Acylation Reactions: This is the primary use of 6-Bromohexanoyl Chloride. It efficiently acylates alcohols to form esters, amines to form amides, and even aromatic rings via Friedel-Crafts acylation.
  • Synthesis of Complex Molecules: The bromoalkyl chain can be further modified. For instance, it can undergo SN2 reactions with various nucleophiles or participate in Grignard reactions to form new C-C bonds. This dual functionality makes it invaluable for constructing intricate molecular architectures.
  • Pharmaceutical and Agrochemical Intermediates: As previously discussed, it's a key precursor in synthesizing active ingredients for pharmaceuticals and crop protection agents. Sourcing from a reliable supplier ensures the quality needed for these regulated industries.
  • Material Science: The compound can be used to modify polymers or create monomers with specific functionalities, impacting the properties of resulting materials.

Tips for Sourcing 6-Bromohexanoyl Chloride

When you need to acquire 6-Bromohexanoyl Chloride for your research or production, consider the following:

  • Purity: For demanding synthetic routes, opt for purities of 98.0% or higher. Always request a COA from your manufacturer.
  • Quantity: Suppliers offer a range of sizes, from grams for lab use to kilograms for pilot-scale or bulk orders.
  • Pricing: Obtain multiple quotes to ensure competitive pricing, but never compromise on quality for cost savings.
  • Supplier Reputation: Work with established chemical suppliers and manufacturers known for their quality and reliability.

By leveraging the reactivity of 6-Bromohexanoyl Chloride and sourcing it wisely from reputable providers, chemists can significantly enhance their capabilities in organic synthesis.
