In the realm of chemical manufacturing and research, securing reliable sources for key raw materials is paramount. For many complex organic syntheses and specialized solvent applications, 1-Chlorobutane, also known as n-Butyl Chloride, stands out as a critical compound. Understanding how to effectively source this chemical, particularly from reputable manufacturers and suppliers, can significantly impact project success and cost-efficiency.

What is 1-Chlorobutane?

1-Chlorobutane (CAS No. 109-69-3) is a colorless, volatile liquid with a distinct pungent odor. Its molecular formula is C4H9Cl, and it possesses excellent solvency for fats, oils, and waxes. Chemically, it's a halogenated hydrocarbon, specifically an alkyl halide, and it plays a significant role as an alkylating agent and a precursor in various synthetic pathways.

Key Applications Driving Demand:

  • Organic Synthesis: 1-Chlorobutane is indispensable for introducing butyl groups into organic molecules. It's a key component in the production of organometallic reagents like n-butyl lithium, which are vital in polymerization processes for the plastics industry, and in the synthesis of specialty chemicals and pharmaceuticals.
  • Pharmaceutical Intermediates: Its role extends to the pharmaceutical sector, where it's used in the synthesis of active pharmaceutical ingredients (APIs) for various therapeutic applications.
  • Solvents and Analytical Chemistry: Its good dissolving properties make it valuable in high-performance liquid chromatography (HPLC), spectrophotometry, and environmental testing.
  • Veterinary Medicine: It also finds application as an anthelmintic (dewormer) in veterinary medicine.

What to Consider When Buying 1-Chlorobutane:

For procurement managers and R&D scientists, several factors are crucial when sourcing 1-Chlorobutane:

  1. Purity: The required purity level is paramount. For analytical applications or sensitive syntheses, high purity grades (e.g., HPLC grade, ≥99.8%) are essential. Manufacturers often specify purity levels using techniques like Gas Chromatography (GC). Always check the Certificate of Analysis (CoA) to verify these specifications.
  2. Grade and Application Suitability: Ensure the grade of 1-Chlorobutane matches your intended use. For instance, solvents for HPLC require specific low residue and low UV absorbance properties.
  3. Supplier Reliability: Partnering with established manufacturers and suppliers, particularly those based in China with a strong track record, ensures consistent quality and timely delivery. Look for suppliers who can provide a stable supply chain and offer competitive pricing.
  4. Safety and Handling: 1-Chlorobutane is highly flammable (Flash Point typically around -12°C or 10°F) and can cause skin and eye irritation. Always review the Safety Data Sheet (SDS) and ensure appropriate handling and storage protocols are in place.
  5. Regulatory Compliance: Verify that the supplier adheres to all relevant safety and environmental regulations.

Finding a Trusted 1-Chlorobutane Manufacturer:

When seeking to buy 1-Chlorobutane, consider manufacturers who can demonstrate consistent production quality and offer technical support. Companies specializing in fine chemicals and intermediates are often the best bet. Online platforms and B2B marketplaces can be a starting point, but due diligence in verifying supplier credentials is key. For those looking to purchase 1-Chlorobutane in bulk, establishing a direct relationship with a manufacturer or a large-scale distributor is often the most efficient approach to secure both quality and competitive pricing.

By understanding these key considerations, procurement professionals can make informed decisions when sourcing 1-Chlorobutane, ensuring the success of their chemical processes and product development.
