Description

Asatra Impurityc (1-Methyl-2-(Methylsulfonyl)-4-Nitro-1H-Imidazole) is a high-purity chemical reference standard and synthetic intermediate. This compound is of critical importance for pharmaceutical research and development, particularly in the quality control and regulatory filing of active pharmaceutical ingredients (APIs). It is primarily required by analytical laboratories, R&D chemists, and quality assurance professionals in the pharmaceutical and fine chemical industries for impurity identification, method validation, and process monitoring.

Application

• Pharmaceutical Impurity Standard: Used as a certified reference material (CRM) for the identification and quantification of related substances in drug substances and products.
• Analytical Method Development: Essential for developing and validating HPLC, UPLC, or GC methods to monitor impurities during API synthesis.
• Process Chemistry Research: Serves as a key intermediate or by-product marker in the synthesis of complex imidazole-based drug molecules.
• Regulatory Compliance & Filing: Critical for preparing regulatory submission documents (e.g., for FDA, EMA) that require full characterization of potential impurities.
• Quality Control (QC) Testing: Employed in routine QC laboratories to ensure batch-to-batch consistency and purity of final APIs.
• Academic & Contract Research: Used in university and CRO settings for pharmacological studies and custom synthesis projects.
