In the industrial chemical landscape, precision and reliability are paramount. m-Tolualdehyde (CAS 620-23-5), also known as 3-Methylbenzaldehyde, is a chemical intermediate whose utility across various sectors, including pharmaceuticals and fragrances, hinges significantly on its purity and well-defined specifications. For chemical engineers, procurement specialists, and R&D scientists, a thorough understanding of these aspects is essential when deciding to buy m-tolualdehyde.

Defining Purity: What Matters for m-Tolualdehyde?

The purity of m-Tolualdehyde is typically expressed as a percentage, often determined by Gas Chromatography (GC) analysis. Common purities range from 95% to over 98%. For applications in organic synthesis, particularly in the pharmaceutical industry, higher purity levels (e.g., ≥ 97% or ≥ 98%) are often required to minimize side reactions and ensure the quality of the final product. Impurities can arise from the synthesis process or degradation during storage, potentially affecting reaction yields or the sensory profile of fragrance compounds. Therefore, when you are looking to purchase m-tolualdehyde, always check the Certificate of Analysis (CoA) provided by the supplier for detailed impurity profiles.

Key Specifications Beyond Purity

While purity is a primary concern, other specifications are equally important for industrial applications of m-tolualdehyde:

  • Appearance: Typically described as a clear liquid, ranging from colorless to pale yellow. Variations might indicate the presence of impurities or degradation.
  • Molecular Formula and Weight: C8H8O and 120.15 g/mol, respectively, are fundamental identifiers.
  • Boiling Point: Around 199 °C, which is relevant for distillation and purification processes.
  • Flash Point: Approximately 173 °F (78 °C), indicating flammability and necessary handling precautions.
  • Density and Refractive Index: These physical constants are useful for quality control checks.

When seeking to buy m-tolualdehyde, understanding these specifications helps in selecting the right grade for your specific industrial process. A dependable manufacturer will readily supply this data.

Sourcing for Industrial Needs: Manufacturer Reliability

For bulk purchases, engaging directly with a manufacturer, especially from regions like China known for efficient chemical production, can offer significant advantages in terms of cost and supply chain stability. Procurement managers should prioritize suppliers who can consistently meet these specifications and provide comprehensive documentation. A supplier that actively markets terms like 'm-tolualdehyde manufacturer' or 'wholesale m-tolualdehyde' often has the capacity for industrial-scale supply.

Conclusion

The performance and reliability of m-tolualdehyde in industrial applications are directly tied to its purity and adherence to specifications. By carefully evaluating supplier data and understanding these critical parameters, businesses can make informed purchasing decisions and ensure the successful implementation of m-tolualdehyde in their processes.
