The pharmaceutical industry operates under the strictest quality control measures to ensure the safety and efficacy of medications. A key aspect of this is the precise identification and quantification of impurities within drug substances and finished products. For a widely used drug like Sildenafil Citrate, maintaining a high level of purity is non-negotiable. This is where compounds like 4-(2-Ethoxybenzamido)-1-methyl-3-propylpyrazole-5-carboxamide (CAS: 139756-03-9) become indispensable as critical pharmaceutical impurity reference standards. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted provider of such high-purity reference materials.

4-(2-Ethoxybenzamido)-1-methyl-3-propylpyrazole-5-carboxamide, with its chemical formula C17H22N4O3 and molecular weight of 330.38, is a recognized impurity and intermediate in the synthesis of Sildenafil. As a reference standard, it allows analytical chemists to develop and validate sensitive methods, such as High-Performance Liquid Chromatography (HPLC), to detect even trace amounts of this specific compound in Sildenafil batches. The ability to accurately measure such impurities is vital for complying with regulatory guidelines from bodies like the FDA and EMA. The rigorous use of Sildenafil impurity reference standards is a hallmark of quality assurance in API manufacturing.

The utility of this compound extends to its role as a key Sildenafil intermediate chemical. Understanding its chemical properties, such as its appearance as a white solid and its solubility characteristics, is crucial for successful integration into synthetic routes. Manufacturers rely on consistent access to such intermediates from reputable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. to maintain their production schedules and product quality. The expertise in handling and characterizing these chemicals ensures that they meet the necessary specifications for both synthesis and analytical use. Without reliable 4-(2-ethoxybenzoyl)amino-2-methyl-5-propylpyrazole-3-carboxamide, maintaining pharmaceutical standards would be significantly more challenging.
