Formaldehyde is used in the production of resins such as urea-formaldehyde and phenol-formaldehyde which are important in making plastics plywood adhesives and coatings. It is also used in textiles to improve wrinkle resistance in disinfectants and in embalming fluids for preserving biological specimens. Additionally it plays a role in the manufacture of fertilizers paints and certain medicines.

Serves as a key building block in polymer synthesis via cross-linking and condensation reactions acts as a reducing agent and provides germicidal properties by denaturing proteins. In vivo trace amounts occur naturally from metabolism but at higher lev

Formaldehyde is the simplest aldehyde and is highly reactive. It is usually found in aqueous solution called formalin. It has strong antiseptic and preservative properties which make it useful in many chemical and biological processes.
