For professionals in the pharmaceutical industry, the quality and consistency of raw materials are of utmost importance. 2,5-Dimethoxybenzaldehyde (CAS 93-02-7) is a vital pharmaceutical intermediate, and understanding its key specifications is crucial for ensuring successful synthesis and product efficacy. This guide details the critical parameters that buyers should look for when sourcing this compound.

The Foundation: Purity and Assay

The primary specification for 2,5-Dimethoxybenzaldehyde is its purity, typically measured by assay. A minimum assay of ≥99.0% is standard for pharmaceutical applications, ensuring that impurities are kept to a minimum. This high purity is essential for downstream reactions, preventing side reactions that could compromise the final API or product.

Physical Characteristics: Appearance and Form

The typical appearance of 2,5-Dimethoxybenzaldehyde is a yellowish crystalline powder. This visual characteristic, along with its physical form, is an initial indicator of product quality. Deviations in color or form might suggest impurities or degradation, highlighting the importance of sourcing from a trusted manufacturer.

Critical Physical Properties

  • Melting Point: A well-defined melting point range, commonly around 48.5-51.5 °C, is another indicator of purity and chemical integrity.
  • Loss on Drying: This specification, usually ≤0.50%, indicates the water content. Lower moisture content is preferred for many synthesis processes to avoid unwanted hydrolysis or side reactions.
  • Heavy Metals and Ignition Residue: Limits for heavy metals (≤50 ppm) and ignition residue (≤0.10%) are also critical for pharmaceutical intermediates, ensuring the absence of metallic contaminants and inorganic impurities.

Why Sourcing Matters: Manufacturer Reliability

When you need to buy 2,5-Dimethoxybenzaldehyde, partnering with a reliable manufacturer and supplier in China offers significant advantages. These suppliers can guarantee consistent product quality, provide detailed Certificates of Analysis (CoA), and ensure a stable supply chain. For R&D scientists and procurement managers, this reliability translates into predictable experimental outcomes and efficient production planning. A manufacturer that adheres to stringent quality control measures is essential for meeting regulatory requirements in the pharmaceutical sector.

Leveraging 2,5-Dimethoxybenzaldehyde in Synthesis

As a key intermediate, 2,5-Dimethoxybenzaldehyde is integral to organic synthesis pathways. Its applications extend beyond pharmaceuticals to include the fragrance industry and dye manufacturing. Ensuring you purchase from a supplier that understands these diverse needs allows for better collaboration and technical support.

In conclusion, meticulous attention to the specifications of 2,5-Dimethoxybenzaldehyde is vital for pharmaceutical synthesis. By prioritizing high purity, well-defined physical properties, and partnering with a dependable manufacturer, organizations can confidently procure this essential chemical intermediate.
