Heptanoic Anhydride, identified by its CAS number 626-27-7, is a chemical compound frequently encountered in organic synthesis. As an anhydride derived from heptanoic acid, it functions as a useful acylating agent, enabling chemists to incorporate the heptanoyl group into various molecular structures. For professionals in the chemical manufacturing sector, R&D departments, and procurement offices, understanding the fundamental properties and applications of Heptanoic Anhydride, along with the best practices for sourcing it, is essential for efficient operations. This guide aims to provide a comprehensive overview for those looking to buy Heptanoic Anhydride, with a particular focus on reliable suppliers, especially those based in China.

Understanding Heptanoic Anhydride: Properties and Specifications

Heptanoic Anhydride, also known as Enanthic Anhydride, has the molecular formula C14H26O3 and a molecular weight of approximately 242.36 g/mol. It is commonly supplied as a liquid, making it easy to handle in standard laboratory and industrial settings. The purity of Heptanoic Anhydride is a key specification, with manufacturers typically offering grades of 97.0% or higher. For critical synthesis processes, such as those in the pharmaceutical or fine chemical industries, sourcing material with verified high purity is crucial. A reliable manufacturer will provide a Certificate of Analysis (CoA) detailing lot-specific quality parameters and a Safety Data Sheet (SDS) for safe handling.

Key Applications in Chemical Synthesis

The primary utility of Heptanoic Anhydride lies in its role as an acylating agent. It reacts readily with nucleophiles like alcohols and amines to form corresponding esters and amides. These reactions are foundational in building complex organic molecules, making Heptanoic Anhydride valuable for:

  • Pharmaceutical Synthesis: Used in the creation of intermediates or active pharmaceutical ingredients (APIs) requiring the heptanoyl moiety.
  • Fine Chemicals: A building block for specialty chemicals, flavors, fragrances, and other high-value compounds.
  • Research and Development: Employed in academic and industrial labs for experimental synthesis and method development.

The efficiency and yield of these processes are directly influenced by the quality of the Heptanoic Anhydride used.

Sourcing Strategies: Finding a Reliable Manufacturer

When you need to buy Heptanoic Anhydride, looking towards China offers significant advantages in terms of cost and availability. The Chinese chemical industry is well-established, with numerous manufacturers capable of producing Heptanoic Anhydride (CAS 626-27-7) to international standards. Key considerations when selecting a supplier include their manufacturing capacity, commitment to quality control, responsiveness to inquiries, and reliable logistics. Standard packaging, such as 25kg/drum, is common, but suppliers may also offer custom solutions. Prioritizing suppliers who provide comprehensive documentation and have a proven track record ensures a more secure procurement process.
