For professionals in the chemical, pharmaceutical, and cosmetic industries, the purity of raw materials like Dibutyl Oxalate (CAS 2050-60-4) is a non-negotiable factor. As a Dibutyl Oxalate manufacturer, we understand that the reliability and success of our clients' processes often depend directly on the quality of the materials they purchase. This article outlines what buyers should look for when evaluating the purity of Dibutyl Oxalate.

The most common specification for Dibutyl Oxalate purity is its assay, typically measured using Gas Chromatography (GC). Reputable suppliers will offer Dibutyl Oxalate with a minimum assay of ≥99.0%. However, for highly sensitive applications, such as pharmaceutical synthesis or advanced cosmetic formulations, even minor deviations can have significant consequences. It is therefore crucial to inquire about the specific analytical methods used and the detection limits for potential impurities.

Beyond the assay percentage, buyers should also consider other critical specifications. These might include the acidity level (e.g., ≤0.50% or ≤0.60%) and water content (e.g., ≤0.15% or ≤0.20%). High acidity can indicate incomplete esterification or degradation, while excess water can interfere with certain reactions or affect product stability. A responsible Dibutyl Oxalate supplier will provide detailed specifications for these parameters.

Quality assurance from a manufacturer is another vital aspect. When you plan to buy Dibutyl Oxalate, look for suppliers who can provide Certificates of Analysis (CoA) for each batch. These documents offer a transparent record of the product's tested properties against established standards. Furthermore, certifications like ISO or GMP (Good Manufacturing Practice) can indicate a manufacturer's commitment to stringent quality management systems, which is especially important for pharmaceutical or food-grade applications, though Dibutyl Oxalate is more common as an industrial chemical or intermediate.

When comparing Dibutyl Oxalate prices from different manufacturers, always ensure you are comparing apples to apples – meaning, products with equivalent purity and specifications. A slightly higher price for a guaranteed high-purity product from a trusted Dibutyl Oxalate supplier in China can prevent costly issues down the line. Prioritize quality and reliable sourcing to ensure the integrity of your final products.
