As an important chemical raw material with the properties of solvent, disinfection and rapid volatilization, isopropanol (IPA for short) has been deeply integrated into medical and health care, industrial production, daily life and many other fields, becoming an "all-round player" that silently contributes to the operation of modern society. In the field of medical disinfection, 70% concentration of isopropanol aqueous solution is recognized as a high-efficiency disinfectant. It can penetrate the cell membranes and protein shells of bacteria and viruses to denature them, and is effective in killing COVID-19, influenza viruses and other pathogens. It is widely used in hand sanitizers, medical wipes and surface disinfection of medical devices, playing a key role especially during the epidemic. In the electronics industry, thanks to its advantages of strong volatility and residue-free decontamination, isopropanol has become a "magic weapon" for cleaning circuit boards and electronic components. It can not only remove flux residues and dust, but also be used for the maintenance of precision parts such as magnetic heads and camera lenses. At the same time, it also serves as a diluent in some manufacturing processes. Its uses are equally extensive in industrial production and daily life. As an excellent solvent, it is an important raw material for paints, inks, glues and other products; as a dehydrating agent, it can accelerate the drying of objects; in households, it can effectively clean glass and stainless steel surfaces, and also remove residual adhesive from stickers. Some daily chemical products such as cosmetics and perfumes also use it as a solvent component. In addition, it is also a common reagent for chemical reactions and biological sample preservation in laboratories. Professionals remind that isopropanol vapor is flammable and explosive. It should be used away from open flames and heat sources, and operated in a well-ventilated environment to avoid inhalation of high-concentration vapor or long-term skin contact, so as to prevent poisoning or dry and chapped skin. From medical epidemic prevention to high-tech manufacturing, from industrial production to home cleaning, isopropanol, with its unique properties, has become an indispensable chemical material across multiple fields, continuously providing support for the development of various industries.
