ABOUT THE PRODUCT

Product Description

Product Description-Formaldehyde CAS#50-00-0


Formaldehyde is the simplest aldehyde. It is a colorless, highly reactive, and toxic gas with a pungent odor at room temperature, and it easily polymerizes into paraformaldehyde. It dissolves well in water, alcohol, and other organic solvents. The main environmental sources are fuel combustion, industrial production, building and decoration materials, and various consumer goods.

Product Applications-Formaldehyde CAS#50-00-0


Formaldehyde is a powerful reducing agent with strong bactericidal properties. It serves as a disinfectant for humans and as an antiseptic and fumigant for animals.


As a key organic chemical feedstock, formaldehyde is widely used in pharmaceuticals, synthetic fibers, resins, plastic preservatives, and reducing agents. Its primary applications include the production of phenolic, urea-formaldehyde, melamine, and polyoxymethylene resins.


It is also used to manufacture MDI, pentaerythritol, hexamethylenetetramine, and butanediol. Additionally, it finds use in chromatographic analysis, sterilization, phenolic resin production, and the preservation of biological specimens.
