For professionals in the chemical industry, particularly those involved in procurement and R&D for pharmaceutical intermediates and fine chemicals, a thorough understanding of product specifications is non-negotiable. 2-Aminoisophthalic Acid, identified by its CAS number 39622-79-2, is a critical compound with specific characteristics that influence its utility. This article aims to demystify these specifications, providing a clear guide for making informed purchasing decisions when you need to buy this important chemical.

What are Chemical Specifications?

Chemical specifications are a set of detailed properties that define a particular chemical compound. They include physical characteristics, purity levels, and other critical parameters that ensure the substance will perform as expected in its intended applications. For a compound like 2-Aminoisophthalic Acid, understanding these specifications is crucial for successful synthesis, quality control, and regulatory compliance.

Key Specifications for 2-Aminoisophthalic Acid (CAS 39622-79-2)

When sourcing 2-Aminoisophthalic Acid from manufacturers or suppliers, you will typically encounter the following key specifications:

  • Appearance: This refers to the physical state and color of the compound. For 2-Aminoisophthalic Acid, the standard description is a white solid. Any significant deviation in color or form might indicate the presence of impurities or degradation.
  • Purity: This is perhaps the most critical specification, especially for pharmaceutical applications. The purity of 2-Aminoisophthalic Acid is commonly stated as a percentage, often ≥97% or ≥98%. Higher purity generally correlates with better performance in synthesis reactions and fewer side products. When you buy, always check the Certificate of Analysis (COA) for lot-specific purity data.
  • Melting Point: The melting point is the temperature at which a solid substance transitions into a liquid. For 2-Aminoisophthalic Acid, a typical melting point range is 312-315°C. A sharp melting point within this range indicates high purity, while a broad or significantly lower range may suggest the presence of impurities.
  • Molecular Formula and Weight: These are fundamental identifiers. For 2-Aminoisophthalic Acid, the molecular formula is C8H7NO4, and its molecular weight is approximately 181.15 g/mol.
  • CAS Number: As mentioned, 39622-79-2 is the unique identifier for 2-Aminoisophthalic Acid, essential for accurate ordering and regulatory documentation.

Why These Specifications Matter to Buyers

For procurement managers and R&D scientists, these specifications directly inform their purchasing decisions:

  • Quality Assurance: Matching product specifications to project requirements ensures that the intermediate will function correctly in synthesis.
  • Cost Efficiency: While higher purity often comes at a higher price, it can lead to more efficient reactions and higher yields, ultimately saving costs.
  • Supplier Evaluation: Comparing specifications from different manufacturers, particularly those based in China, helps in identifying reliable and quality-focused suppliers.
  • Process Reproducibility: Consistent specifications from batch to batch are vital for reproducible manufacturing processes.

Sourcing with Confidence

When you need to purchase 2-Aminoisophthalic Acid, partnering with a manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. that provides clear and accurate specification data is key. Understanding these details empowers you to make informed decisions, secure high-quality materials, and ensure the success of your chemical synthesis projects. Always prioritize suppliers who offer transparent information and comprehensive documentation for their products.
