Methanal, commonly known as formaldehyde, is a simple organic compound with the chemical formula CH₂O. It is a colorless gas at room temperature and has a strong, pungent odor. Methanal is widely used in various industries, including the production of resins, plastics, and textiles, as well as in the preservation of biological specimens. In addition to its industrial applications, methanal is also found in household products such as disinfectants and preservatives. Due to its potential health risks, exposure to high levels of methanal can cause irritation to the eyes, skin, and respiratory system, making safety precautions essential when handling it.
