When engaging in the procurement of chemical compounds, especially those destined for sensitive applications like pharmaceuticals and advanced materials, a thorough understanding of product specifications is non-negotiable. For 2-Thiopheneacetic Acid (CAS 1918-77-0), delving into purity levels, typical properties, and the significance of accurate documentation is paramount for researchers, formulators, and procurement managers alike.

What are the Key Specifications for 2-Thiopheneacetic Acid?

The primary identifier for this compound is its CAS number: 1918-77-0. Beyond this, several critical specifications dictate its suitability for various applications:

  • Appearance: Typically described as a white to light yellow crystalline powder. Deviations from this can indicate impurities or degradation.
  • Purity: This is arguably the most critical specification. For 2-Thiopheneacetic Acid, purity levels often range from ≥96% to ≥99%. For pharmaceutical intermediate use, ≥99% purity is generally preferred to minimize downstream contamination and ensure efficacy. Reputable suppliers will provide a Certificate of Analysis (COA) detailing the specific purity for each batch, often determined by analytical methods like Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC).
  • Molecular Formula & Weight: C6H6O2S and 142.17 g/mol are standard. These values are foundational for stoichiometric calculations in synthesis.
  • Melting Point: Typically around 63-67 °C. This property is a good indicator of purity; a sharp melting point within the expected range suggests a high-quality product.
  • Solubility: Information on solubility in common solvents (e.g., sparingly in chloroform, slightly in methanol, soluble in water, ethanol, ether) is vital for formulation and reaction planning.
  • EINECS Number: 217-639-8 is another identifier often listed.

Why are These Specifications Important for Buyers?

For any B2B buyer, particularly those in the pharmaceutical and fine chemical sectors, understanding these specifications directly impacts their operations:

  • Product Performance: The purity and physical characteristics of 2-Thiopheneacetic Acid directly influence the yield, selectivity, and success rate of synthetic reactions or the efficacy of final products.
  • Regulatory Compliance: In the pharmaceutical industry, adherence to strict regulatory guidelines is mandatory. Using materials that meet predefined purity standards is essential for drug approval processes.
  • Cost-Effectiveness: While higher purity often correlates with a higher price, using a lower-purity material where a high-purity one is required can lead to costly rework, failed batches, or ineffective final products. A careful balance must be struck based on the application's demands.
  • Supplier Selection: A supplier who clearly lists these specifications, provides detailed COAs, and is transparent about their analytical methods is generally more reliable. When you buy 2-thiopheneacetic acid, always ask for these documents.

Sourcing High-Purity 2-Thiopheneacetic Acid

When seeking to purchase 2-thiopheneacetic acid, especially for critical applications, prioritizing suppliers who guarantee high purity (e.g., ≥99%) is crucial. Working with an experienced 2-thiopheneacetic acid manufacturer, perhaps based in China, can offer both quality and competitive pricing. Always ensure that the product you receive aligns with the specifications you require, backed by comprehensive documentation.
