For procurement managers tasked with sourcing chemical raw materials, understanding product specifications is fundamental to ensuring quality and suitability for intended applications. Isopropyl Alcohol (IPA), with CAS number 67-63-0, is a prime example where precise specifications directly influence its effectiveness in various industries, from pharmaceuticals to electronics. If you're looking to buy Isopropyl Alcohol, this guide will help you navigate the essential specifications.

Key Specifications to Scrutinize for Isopropyl Alcohol:

  • Assay/Purity: This is perhaps the most critical specification. For most industrial uses, particularly in pharmaceuticals, cosmetics, and electronics, a high purity of 99.7% or higher is required. This indicates the percentage of actual IPA in the product. Lower purities might be acceptable for less demanding cleaning applications, but it's crucial to match the grade to the use.
  • Appearance: IPA should be a clear, colorless liquid. Any cloudiness or discoloration can indicate contamination or degradation.
  • Color (Pt-Co Scale): This quantifies the color intensity, usually on the Platinum-Cobalt scale. Lower numbers (e.g., ≤10) indicate a clearer product, which is desirable for many applications.
  • Moisture Content: Water can interfere with many chemical reactions and cleaning processes. Low moisture content (e.g., ≤0.20%) is often specified, especially for anhydrous or solvent applications.
  • Acidity (as Acetic Acid): Measured in ppm (parts per million), acidity indicates the presence of acidic impurities. Low acidity is crucial for applications where pH sensitivity is a concern.
  • Evaporation Residue: This measures the non-volatile content left behind after IPA evaporates. For cleaning applications, a very low residue (e.g., ≤0.005%) is essential to avoid leaving unwanted films on surfaces.
  • Acidity (as CH3COOH): Similar to the above, this measures the content of acetic acid impurities.
  • Hydroxyl Content: While IPA is an alcohol, this specification might refer to specific hydroxyl-related impurities or by-products depending on the grade.
  • Sulfur Content (S, ppm): In certain sensitive applications, particularly in electronics, even trace amounts of sulfur can be detrimental. Low ppm levels are often specified.

Why These Specifications Matter to Your Business:

Cost-Effectiveness: While higher purity grades might have a higher price, they often prove more cost-effective in the long run by preventing production failures, rework, or product defects caused by impurities.

Performance: The right specifications ensure IPA performs optimally as a solvent, disinfectant, or reactant in your specific application.

Safety and Compliance: Meeting regulatory standards often depends on adhering to specific impurity limits.
