In the rigorous environment of chemical and pharmaceutical manufacturing, the quality of raw materials directly dictates the integrity and performance of the final product. Dimetridazole powder (CAS 551-92-8), a compound widely used as a pharmaceutical intermediate and in agrochemical formulations, is no exception. Adherence to strict quality control measures and precise specifications is paramount to ensure its effectiveness and safety.

The core of quality control for Dimetridazole powder begins with its assay and purity. Reputable manufacturers typically specify a purity of 98% or higher, often verified through analytical techniques such as High-Performance Liquid Chromatography (HPLC). This high level of purity is crucial, especially for pharmaceutical applications where even minor impurities can have significant consequences on drug efficacy and patient safety. The assay confirms the concentration of the active compound, ensuring it meets the required dosage and performance benchmarks.

Beyond chemical purity, the physical characteristics of Dimetridazole powder are also meticulously controlled. The typical appearance is described as a white to cream-colored crystalline powder. Consistent particle size, often specified by mesh size (e.g., 100% pass 80 mesh), is another important parameter. This uniformity affects solubility, flowability, and reactivity in manufacturing processes, contributing to batch-to-batch consistency.

Key specifications commonly associated with Dimetridazole powder include:

  • Assay/Purity: ≥98% (HPLC)
  • Appearance: White crystalline powder
  • Loss on Drying: Typically ≤5.0%
  • Ash Content: Typically ≤5.0%
  • Heavy Metals: Adherence to strict limits, often specified in ppm (e.g., Pb ≤2.0 mg/kg).
  • Microbiological Limits: Negative for specific contaminants like E. coli and Salmonella, with controlled Total Plate Count and Yeast & Mold levels.

The presence of certifications like GMP, HSE, ISO 9001, USP, and BP further underscores a manufacturer's commitment to quality. These certifications indicate that the production processes and quality management systems are audited and conform to international standards. For buyers, seeking Dimetridazole powder with these certifications provides an additional layer of assurance regarding its suitability for sensitive applications.

Furthermore, proper handling and storage conditions are integral to maintaining the quality of Dimetridazole powder. Recommendations often include storing it in a cool, dry place, away from direct light and incompatible materials like strong oxidizing agents, as it can be heat and air sensitive. The packaging, such as foil bags or tightly sealed containers, is designed to protect the compound's integrity during transport and storage.

In essence, the stringent adherence to specifications and robust quality control for Dimetridazole powder ensures its reliability as a critical ingredient. By prioritizing suppliers who meet these standards, chemical manufacturers can safeguard the quality of their own products and contribute to the advancement of both pharmaceutical and agrochemical industries.
