High-quality pharmaceutical intermediates must comply with strict regulatory standards. These standards are set by organizations such as the FDA (Food and Drug Administration) and EMA (European Medicines Agency) to ensure the safety and efficacy of medications. The production process involves precise control of various parameters, including temperature, pH, and purity levels. For instance, ethylene glycol diacetate and sodium cumenesulfonate are common intermediates that must be produced under controlled conditions to maintain their quality and effectiveness.
