For any industrial process reliant on chemical inputs, the purity and precise specifications of those materials are not just details; they are critical determinants of product quality, process efficiency, and overall cost-effectiveness. m-Xylene (CAS 108-38-3), a widely used aromatic hydrocarbon, is no exception. Understanding its specifications is paramount for procurement managers, R&D scientists, and formulation chemists.

Why Purity Matters for m-Xylene

m-Xylene is valued for its role as a chemical intermediate. In this capacity, it undergoes further chemical reactions to form more complex compounds. The presence of impurities, even in small amounts, can:

  • Interfere with Reactions: Impurities can act as inhibitors or catalysts, leading to unwanted side reactions, reduced yields, or entirely different product outcomes.
  • Affect Product Quality: In applications like pharmaceuticals, fragrances, or dyes, even trace impurities can alter the final product's color, odor, efficacy, or safety profile.
  • Damage Equipment: Certain impurities might be corrosive or reactive, potentially damaging processing equipment over time.
  • Increase Costs: Dealing with off-spec materials, reprocessing, or product rejection due to impurities significantly increases operational costs.

Key Specifications to Consider When Buying m-Xylene

When sourcing m-Xylene, whether for laboratory research or large-scale industrial manufacturing, several specifications are crucial:

  1. Assay (Purity): This is the most fundamental specification, indicating the percentage of m-Xylene in the product. For most demanding applications, an assay of ≥99.5% is often required, ensuring high chemical integrity. We pride ourselves on supplying m-xylene that consistently meets or exceeds this standard.
  2. Distillation Range: The narrowness of the distillation range provides an indication of the product's overall purity and the absence of other closely boiling isomers or impurities. A tight range, such as 137.6~140.8 °C, is a hallmark of high-quality m-xylene.
  3. Chroma (Color): Color is often assessed using scales like Pt/Co. A low chroma value (e.g., ≤10 AHPA) indicates a colorless product, which is essential for applications where color is critical, such as in pharmaceuticals and certain dyes.
  4. Non-Arene Content: This specification refers to the percentage of non-aromatic hydrocarbons present. Low non-arene content (e.g., ≤0.001% v/v) is critical for ensuring that the product is predominantly m-Xylene and free from diluting or interfering aliphatic compounds.
  5. Water Content: For moisture-sensitive reactions, specifying maximum water content (often measured by Karl Fischer titration) is vital.
