In the realm of chemical synthesis and research, the quality of starting materials is non-negotiable. For a specialized intermediate like 3-Bromobicyclo[4.2.0]octa-1,3,5-triene (CAS 1073-39-8), understanding and verifying its quality is paramount for successful outcomes. This guide is designed for R&D scientists and procurement teams to understand the key quality indicators when sourcing this vital compound.

Understanding Key Quality Parameters

When you intend to buy 3-Bromobicyclo[4.2.0]octa-1,3,5-triene, pay close attention to the following quality aspects:

  • Purity: This is arguably the most critical parameter. High-purity 3-Bromobicyclo[4.2.0]octa-1,3,5-triene, typically specified as 99% min, ensures predictable reactivity and minimizes side reactions. Impurities can lead to lower yields, difficult purifications, and unreliable experimental results.
  • Appearance: The product's physical state and color are important initial indicators. For this compound, it is usually described as a colorless liquid. Any deviation from this description warrants further investigation.
  • CAS Number Accuracy: Always confirm the CAS number (1073-39-8) is correct for the product you are ordering. This is a universal identifier that prevents mix-ups.
  • Molecular Formula and Weight: Verification of the molecular formula (C8H7Br) and molecular weight (183.045 g/mol) ensures you are receiving the correct chemical entity.
  • Physical Properties: Melting point (94-97 °C) and boiling point (221.4±29.0 °C) are also key identifiers.

Ensuring Quality Assurance from Your Supplier

To guarantee you are sourcing high-quality 3-Bromobicyclo[4.2.0]octa-1,3,5-triene, consider these practices when engaging with a manufacturer or supplier:

  • Request a Certificate of Analysis (CoA): A CoA is a vital document that details the specific batch's analytical results, including purity, impurity profiles, and other relevant physical properties. Reputable suppliers will readily provide this.
  • Obtain Free Samples: Before placing a bulk order, always request and thoroughly test a free sample. This is the best way to confirm the product meets your laboratory's requirements.
  • Verify Supplier Credentials: Look for suppliers with established reputations and certifications. Companies like NINGBO INNO PHARMCHEM CO.,LTD. emphasize quality and reliability in their operations.
  • Understand Storage and Handling Recommendations: Proper storage conditions (e.g., 4-8°C) are crucial for maintaining product integrity. Ensure the supplier provides clear guidance.

By prioritizing these quality assurance measures, researchers and procurement professionals can confidently purchase 3-Bromobicyclo[4.2.0]octa-1,3,5-triene, knowing they are using a reliable and high-performing chemical for their critical synthetic and research endeavors.
