CAS 50-00-0: Formaldehyde

Description: Formaldehyde, with the CAS number 50-00-0, is a colorless, flammable gas at room temperature, characterized by its strong, pungent odor. It is the simplest aldehyde, with the molecular formula CH₂O. Formaldehyde is highly soluble in water, forming a solution known as formalin, which typically contains about 37% formaldehyde by weight. This compound is widely used in various industries, including as a preservative in biological laboratories, in the production of resins and plastics, and as a disinfectant. Formaldehyde is known for its reactivity, particularly in polymerization and condensation reactions, making it valuable in synthetic chemistry. However, it is also recognized as a potential health hazard; exposure can cause irritation of the eyes, skin, and respiratory system, and it is classified as a probable human carcinogen. Due to its widespread use and associated health risks, formaldehyde is subject to regulatory controls in many countries to limit exposure and ensure safety in its applications.
