The procurement of chemical intermediates is a critical process, especially within the pharmaceutical industry where the quality of starting materials directly impacts the final product's safety and efficacy. 5-Chlorothiophene-2-carboxylic acid (CAS 24065-33-6) is a vital intermediate, most notably for the synthesis of Rivaroxaban, and ensuring its quality is paramount. For procurement managers and R&D scientists seeking to buy 5-Chlorothiophene-2-carboxylic acid, a structured approach to quality assurance is essential.

Key Quality Parameters to Scrutinize:

  • Purity: This is the most critical parameter. Pharmaceutical-grade intermediates typically require purity levels of 98% or higher, often verified by High-Performance Liquid Chromatography (HPLC). Always request a Certificate of Analysis (COA) that details the purity and the analytical method used.
  • Appearance: While often described as a white to light yellow crystal powder, any significant deviation from this can indicate potential issues with handling or synthesis.
  • Impurities: Beyond the main compound, understanding the impurity profile is crucial. Suppliers should be able to provide information on known impurities and their acceptable limits, especially for critical applications like API synthesis.
  • Stability and Storage: Information on the compound's stability under various conditions and recommended storage (e.g., temperature, protection from light) ensures that the material remains viable until use.
  • CAS Number Verification: Always confirm the CAS number (24065-33-6) matches the chemical you intend to procure.

Vetting Your Suppliers

When you look to purchase 5-Chlorothiophene-2-carboxylic acid, selecting a reliable supplier is as important as the product itself. A reputable manufacturer or distributor will:

  • Provide comprehensive documentation (COA, SDS).
  • Maintain consistent product quality across batches.
  • Have robust quality control systems in place (e.g., ISO certification).
  • Offer competitive pricing and transparent terms.
  • Demonstrate a stable supply chain and reliable delivery.
