Definition of formaldehyde

The word "formaldehyde" comes from two chemical terms. "Formal" refers to the chemical group methylene (-CH2-) which is derived from formaldehyde (CH2O). "Hydros" is a chemical prefix meaning water (H2O) because formaldehyde has a hydroxy (-OH) group and while not containing water, it can associate with water molecules. Formaldehyde, scientifically known as methanal (CH2O), is a colorless, pungent-smelling gas at room temperature but a liquid below -19°C (0°F). It's been known since ancient times as a preservative due to its strong bonding ability with organic molecules, which slows down chemical reactions within a cell. In the 19th century, scientists noted the preservative qualities of formaldehyde-containing plant extracts and named the chemical compound derived from it "formalin." Then in 1881, German chemist Carl Liebermeister accurately described its chemical structure, giving it the term "formaldehyde". Today, formaldehyde is mainly used in industrial applications, such as in the production of paper, textiles, and building materials. However, it's also a natural byproduct of human metabolism and is found in small amounts in our bodies and in the environment. Unfortunately, exposure to high levels of formaldehyde has been linked to various health issues, including irritation of the nose, eyes, and throat, allergic reactions, and prevented cell reproduction, potentially leading to cancer.
