"High purity" refers to the quality of a substance that contains a minimal amount of impurities or contaminants. This term is often used in various fields, including chemistry, pharmaceuticals, and materials science, where the presence of unwanted substances can affect the performance and safety of products. High purity materials are essential for applications that require precise chemical reactions or consistent performance. In the context of pharmaceuticals, high purity is crucial for ensuring the safety and efficacy of medications. For example, active pharmaceutical ingredients (APIs) must be produced with high purity to avoid adverse reactions in patients. Similarly, in electronics, high purity materials are necessary for manufacturing components that function reliably in devices.
