According to experts in the chemical industry of chemical reagent companies, chemical reagents are relative standard substances for conducting chemical research and component analysis, and are an important condition for technological progress. They are mainly suitable for the synthesis, separation, qualitative and quantitative analysis of substances. In other words, they are the eyes of chemical reagent workers. In the daily work of factories, schools, hospitals, and research institutes, chemical reagents are indispensable.
At present, chemical reagent companies are mainly distributed in various industries such as industry, agriculture, healthcare, life sciences, biotechnology, inspection and quarantine, environmental protection, energy development, national defense and military industry, scientific research, and national economy. However, it is still difficult to provide an accurate definition of what "chemical reagents" are and what they contain. Early chemical reagents only referred to pure chemical drugs used in chemical analysis and experiments to determine the composition or composition of substances.
Later, it was expanded to refer to "chemical drugs used to achieve chemical reactions", and now "chemical reagents" refer to chemical drugs that have already exceeded this category. Some people believe that "chemicals used in scientific experiments" can be referred to as "chemical reagents". A more comprehensive definition of chemical reagents can be: compounds or elemental substances of various purity levels used in chemical experiments, chemical analysis, chemical research, and other experiments.
