This chemical is primarily used as a Certified Reference Material (CRM) for accurately determining and verifying the water content in various liquid samples. It plays a critical role in quality control and assurance processes across industries such as pharmaceuticals, food and beverage, and chemical manufacturing. By providing a reliable standard, it ensures the precision of analytical methods like Karl Fischer titration, which is widely used to measure water content. This helps in maintaining product consistency, meeting regulatory standards, and ensuring the safety and efficacy of end products. Additionally, it is essential for calibration and validation of laboratory instruments, enhancing the accuracy and reliability of test results.
