Chemical Uses
The production of a chemical is a process that involves several stages, from synthesis to purification. The processes used to create bulk chemicals are often simpler than those used to produce fine chemicals. However, the processes that create fine chemicals require more careful handling to avoid impurities. The process of purification also eliminates by-products. The differences between fine and bulk chemicals are largely due to the level of complexity of their molecular structure.
Fine chemicals are produced individually, with a high cost per gram, and are used for special, low-volume applications. Research chemicals are expensive because they are used to screen substances for pharmaceutical activity. While the latter are low-cost, they can have high purity and a high CAS index. In contrast, fine chemicals can be classified as biocides, pharmaceuticals, and biocides. The cost of fine chemicals depends on their quantity, purity, and manufacturing process.
Both organic and inorganic chemistry can be used to develop medicines. Both organic and inorganic chemicals have their uses. Inorganic substances, such as inorganic salts, are useful for building different materials. Inorganic materials, on the other hand, contain carbon, such as fertilizers. A mixture of different compounds, like polyethylene, can be classified as pure substances. But there are some exceptions to these rules. As a general rule, polymers can be divided into three groups: solid, liquid, or gas.
The chemical term ‘compound’ refers to the simplest form of a chemical compound. All chemical substances can be combined to form compounds. For example, the painkiller Naproxen is a compound that is systematically named 6-(hydroxymethyloxane-2,3,4,5-tetrol). This method is used to refer to natural products and pharmaceuticals that are synthesized in a laboratory. The American Chemical Society has estimated that about 177 million substances are known.
