Formaldehyde is an organic compound with the chemical formula CH₂O and CAS Number 50-00-0 for formaldehyde itself. It is a colourless gas at room temperature and is commonly supplied as an aqueous solution known as formalin. The concentration, stabiliser content, and properties of the supplied solution depend on the product specification.

Formaldehyde is valued for its ability to react with biological and organic materials. Common laboratory applications include tissue fixation, preservation of biological specimens, histological preparation, and chemical research. It is also used in selected chemical manufacturing processes and specialised industrial applications.

For laboratory use, the appropriate concentration and grade should be selected according to the requirements of the intended procedure. Product specifications should clearly identify whether the material is supplied as formaldehyde solution or another formulation.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications, subject to applicable chemical regulations.
