For any B2B buyer in the chemical industry, understanding the precise specifications and quality control measures for a product like Cyanoacetic Acid (CAS 372-09-8) is paramount. This fundamental organic compound, crucial for a variety of applications from pharmaceuticals to adhesives, requires careful sourcing to ensure optimal performance in synthesis processes. Manufacturers in China, a major global supplier, often provide detailed information that buyers should leverage.

Key Specifications for Cyanoacetic Acid: What Buyers Need to Know

When evaluating Cyanoacetic Acid from a potential supplier, several key parameters stand out:

  • Purity: The most commonly cited purity level for industrial-grade Cyanoacetic Acid is ≥98.00%. For specialized applications, higher purities might be required, so it's essential to confirm this with your Cyanoacetic Acid manufacturer. Purity directly impacts reaction yields and the quality of the final product.
  • Appearance: Typically described as a 'White to light beige crystalline solid' or 'White to slightly yellowish crystalline hygroscopic solid'. Any deviation from this standard appearance, especially significant discoloration, could indicate impurities or degradation.
  • CAS Number: The identifier 372-09-8 is critical for ensuring you are sourcing the correct chemical compound.
  • Molecular Formula and Weight: C3H3NO2 and 85.06 g/mol are standard identifiers that should be consistent across all reputable suppliers.
  • Melting Point: Often listed as around 65°C (though some sources cite a range like 64-68°C). This physical property is a good indicator of purity.
  • Solubility: Usually noted as soluble in water, ethanol, and ether.

Quality Control Measures from Manufacturers

Reputable manufacturers, particularly those catering to international markets, implement robust quality control (QC) measures. These typically include:

  • In-house Laboratory Testing: Utilizing techniques like Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC) to verify purity and identify potential impurities.
  • Batch Consistency: Implementing strict protocols to ensure that each production batch meets the established specifications.
  • Certifications: Many suppliers may hold ISO certifications, demonstrating their commitment to quality management systems.
  • Documentation: Providing Certificates of Analysis (CoA) for each batch, detailing the QC test results, and Material Safety Data Sheets (MSDS) with handling and safety information.

Making an Informed Purchase Decision

When you purchase Cyanoacetic Acid, asking for a Certificate of Analysis is standard practice. This document is your assurance of the product's quality. Comparing the Cyanoacetic Acid price from different suppliers should always be done in conjunction with a review of their quality control processes and specifications. A slightly higher price from a supplier with proven quality and strong QC might be more cost-effective in the long run, preventing costly batch failures or rework.

For businesses looking to buy Cyanoacetic Acid, especially in bulk, a transparent relationship with a trusted Cyanoacetic Acid supplier who prioritizes quality control is essential for success.
