The production of life-saving pharmaceuticals is a meticulous process that demands unwavering commitment to quality at every stage. This commitment is particularly evident in the manufacturing of pharmaceutical intermediates, the essential building blocks for Active Pharmaceutical Ingredients (APIs). A prime example is 2-Butyl-3-(3,5-diiodo-4-hydroxybenzoyl)benzofuran (CAS 1951-26-4), a critical intermediate used in the synthesis of Amiodarone hydrochloride, a vital medication for patients with cardiac arrhythmias.

Ensuring the quality of 2-Butyl-3-(3,5-diiodo-4-hydroxybenzoyl)benzofuran involves rigorous testing and adherence to strict specifications. Its molecular formula, C19H16I2O3, and molecular weight of 546.14 g/mol, are fundamental identifiers. The physical appearance, described as an off-white crystalline powder, is subject to scrutiny. More critically, the assay purity, mandated to be between 98.0% and 102.0%, along with stringent limits on single impurities (≤0.25%) and total impurities (≤0.5%), guarantees that the intermediate will not compromise the quality of the final drug product. The iodine content, specified between 45.5% and 47.5%, is another key quality parameter.

For pharmaceutical companies, reliable sourcing of such intermediates is paramount. The ability to procure 2-Butyl-3-(3,5-diiodo-4-hydroxybenzoyl)benzofuran from trusted manufacturers, such as NINGBO INNO PHARMCHEM CO.,LTD., is essential for maintaining the integrity of their drug manufacturing processes. This supply chain reliability ensures that drugs for conditions like myocardial infarction and angina pectoris can be produced consistently, meeting patient needs.

The emphasis on quality extends to the recommended storage conditions: refrigeration in a tightly closed container within a dry, well-ventilated environment. These measures are in place to prevent degradation and maintain the intermediate's chemical stability, which is crucial for reproducible synthesis outcomes. The pharmaceutical industry's dedication to quality assurance for intermediates like this demonstrates a proactive approach to patient safety and therapeutic efficacy.

In conclusion, the quality assurance surrounding intermediates such as 2-Butyl-3-(3,5-diiodo-4-hydroxybenzoyl)benzofuran is a critical determinant of the final pharmaceutical product's success. By maintaining stringent quality controls and fostering reliable supplier relationships, the industry ensures that essential medications reach patients effectively and safely.
