pH adjustment is another critical aspect of water treatment. Chemicals such as lime (calcium hydroxide) and sodium hydroxide are frequently added to increase the pH of acidic water, while sulfuric acid can be used to lower the pH of alkaline water. Maintaining the appropriate pH is essential not only for optimizing the effectiveness of disinfectants and coagulants but also for preventing corrosion in pipes and fixtures, which can lead to additional contamination.

Moreover, the relationship between pharmaceutical companies and intermediates manufacturers is often collaborative. These manufacturers work closely with their clients during the drug development process to provide not only the intermediates but also insights into chemical synthesis and process optimization. This collaboration can significantly shorten the time-to-market for new drugs and can also lead to cost savings in the overall manufacturing process. As regulatory hurdles increase, the ability of intermediates manufacturers to navigate complex compliance requirements also becomes a valuable asset for pharmaceutical companies.

The journey of an API begins in the laboratory, where medicinal chemistry focuses on discovering and optimizing compounds that can interact with biological targets, such as enzymes or receptors. Through rigorous research and development, promising candidates undergo preclinical testing followed by several phases of clinical trials to assess their safety and efficacy in humans.
Regulatory guidelines dictate various stability testing protocols to ensure consistency and reliability in the results. The International Council for Harmonisation (ICH) guidelines outline the requirements for stability testing, emphasizing a science-based approach and risk assessment to optimize stability testing protocols. These guidelines serve as a harmonized standard, helping facilitate international trade and ensuring that patients receive safe and effective medicines regardless of where they are produced.
