For professionals in the chemical industry, particularly those involved in advanced synthesis and material science, understanding the precise specifications and quality assurance protocols for key intermediates like 1-Bromoperfluorohexane (CAS 335-56-8) is essential. This article provides a deep dive into these aspects, guiding buyers on what to look for when sourcing this valuable fluorochemical.

Decoding the Specifications of 1-Bromoperfluorohexane (CAS 335-56-8)
1-Bromoperfluorohexane, a compound with the chemical formula C6BrF13, is a perfluorinated alkane derivative. When you intend to buy this compound, its specifications dictate its suitability for your intended application, such as its use in the preparation of perfluorononanal.

Key specifications to consider:

  • CAS Number: 335-56-8. This unique identifier ensures you are referencing the correct chemical entity.
  • Molecular Formula: C6BrF13. This indicates the exact atomic composition.
  • Molecular Weight: Approximately 398.95 g/mol. Essential for stoichiometric calculations in reactions.
  • Appearance: Typically described as a colorless liquid. Any deviation could indicate impurities or degradation.
  • Purity: Manufacturers usually offer grades with purity levels exceeding 97.0% or 99.0% (GC). Higher purity is often required for sensitive synthesis.
  • Boiling Point: Around 97-100°C at atmospheric pressure. This property is important for distillation and purification processes.
  • Density: Typically around 1.871 g/mL at 25°C. Useful for physical handling and volume-to-mass conversions.
  • Storage Conditions: Often recommended to store at room temperature or refrigerated (e.g., 2-8°C) in tightly sealed containers to maintain stability.

Ensuring Quality Assurance: What Buyers Should Demand
Quality assurance is not just a claim; it's a demonstrable process. When you buy 1-Bromoperfluorohexane, here’s how to ensure you’re getting a quality product:

1. Certificate of Analysis (COA): This is the most critical document. A comprehensive COA should detail the product’s specifications, the batch number, testing methods used (e.g., Gas Chromatography for purity), and the results. Always request and review the COA for every order.

2. Supplier Reputation: Partner with manufacturers who have a strong reputation for quality and consistency. Look for companies with established quality management systems (e.g., ISO 9001). A supplier that readily provides technical documentation and answers questions thoroughly demonstrates a commitment to quality.

3. Manufacturing Site Information: Knowing where the chemical is manufactured and the company’s production capabilities can provide confidence in the supply chain. Working with a direct manufacturer, especially one with advanced facilities in China, can often lead to better quality control and pricing.

4. Batch Traceability: A good supplier will have robust systems for batch traceability, allowing them to track the origin and production history of each lot. This is crucial for troubleshooting and quality management.

5. Sample Testing: Always use the opportunity to test samples from potential suppliers in your own laboratory. This is the ultimate validation of product quality and suitability for your specific processes.
