For chemists, formulators, and procurement specialists, a thorough understanding of chemical properties is the bedrock of successful product development and manufacturing. 1,6-Dichlorohexane (CAS 2163-00-0), also known as hexamethylene dichloride, is a compound that offers a unique combination of characteristics, making it a valuable commodity in the chemical industry. This article aims to provide a comprehensive overview of its key properties and offer guidance on identifying reputable suppliers, particularly those operating out of China, ensuring you can confidently buy this essential chemical.

Key Properties of 1,6-Dichlorohexane

1,6-Dichlorohexane is characterized by its specific physical and chemical attributes:

  • Chemical Structure: With the molecular formula C6H12Cl2 and a molecular weight of approximately 155.06 g/mol, it is a linear alkane with chlorine atoms at both ends of the six-carbon chain. This bifunctionality is key to its reactivity.
  • Appearance: Typically, it presents as a colorless to slight yellow liquid. This visual characteristic is a primary indicator of its quality and purity when received from a supplier.
  • Purity: Industrial and research applications commonly require a purity of 99% or higher, often verified by Gas Chromatography (GC). High purity is critical for ensuring predictable reaction kinetics and the integrity of synthesized products.
  • Reactivity: The terminal chlorine atoms are susceptible to nucleophilic substitution reactions, making 1,6-Dichlorohexane a versatile intermediate. It can readily react with nucleophiles to form new carbon-heteroatom bonds, enabling chain extension or cyclization.
  • Physical State: It is a liquid at room temperature, with a boiling point around 204-205°C and a melting point of -13°C. Its flash point is reported around 73°C, classifying it as a combustible liquid.
  • Solubility: It is generally soluble in common organic solvents but has limited solubility in water.

Selecting a Reliable Supplier for 1,6-Dichlorohexane

When you are ready to purchase 1,6-Dichlorohexane (CAS 2163-00-0), especially from the vast Chinese market, consider the following to ensure you are working with a reputable manufacturer:

  • Verify Purity and Specifications: Confirm that the supplier provides a detailed Certificate of Analysis (CoA) for each batch, clearly stating the purity level and the analytical methods used.
  • Manufacturer Experience: Look for suppliers who have established themselves as reliable manufacturers of fine chemicals. Companies with ISO certifications and long-standing operations are often preferred.
  • Competitive Pricing and MOQs: Obtain quotes for the quantities you need. Understand the minimum order quantities (MOQs) and negotiate pricing for bulk purchases to ensure cost-effectiveness.
  • Safety Data Sheets (SDS): Always request and review the SDS to understand safe handling, storage, and disposal procedures.
  • Customer Service: A responsive and knowledgeable sales team can significantly streamline the procurement process and provide valuable support.

For businesses aiming to buy high-quality 1,6-Dichlorohexane, understanding its properties and diligently selecting a trusted China manufacturer is paramount. By focusing on purity, supplier reliability, and comprehensive documentation, you can secure a consistent and high-quality supply of this essential chemical for your operations.
