epäpuhtaustyypit

Epäpuhtaustyypit refers to the different categories of impurities that can be found in a substance. These impurities can originate from various sources during the manufacturing process, storage, or even from the raw materials themselves. Understanding the types of impurities present is crucial for quality control, safety, and determining the suitability of a substance for its intended use.

One common type of impurity is related substances. These are chemically similar to the main compound but differ in structure, often due to side reactions during synthesis or degradation over time. Process impurities are another category, arising from reagents, catalysts, solvents, or intermediates used in the manufacturing process that have not been completely removed.

Inorganic impurities include salts, heavy metals, or other mineral-based contaminants that might be present in the raw materials or introduced through equipment. Residual solvents are organic compounds used in the manufacturing process that remain in the final product. Their presence is strictly controlled due to potential toxicity.

Degradation products are impurities that form when the main substance breaks down due to factors like heat, light, moisture, or oxidation. Polymorphs are different crystalline forms of the same compound, and while not always considered an impurity in the traditional sense, they can affect the physical properties and performance of the substance. Identification and quantification of these epäpuhtaustyypit are essential steps in analytical chemistry and pharmaceutical quality assurance.
