Product Specifications

Paraformaldehyde is a polymeric form of formaldehyde with the general chemical formula (CH₂O)ₙ and CAS Number 30525-89-4. It is commonly supplied as a white crystalline powder or solid with a characteristic formaldehyde odour. It is generally insoluble in cold water but depolymerises under suitable conditions to release formaldehyde.

Paraformaldehyde is valued for its applications in biological and laboratory research. Common applications include preparation of tissue fixatives, cell fixation, histology, immunohistochemistry, microscopy, and preservation of biological specimens. It is also used in selected chemical manufacturing processes and specialised laboratory formulations.

Its chemical properties make Paraformaldehyde useful in biological research, life sciences, histological applications, and general laboratory preparation. The appropriate grade and purity should be selected according to the requirements of the intended application.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.

Safety Note: Paraformaldehyde is a hazardous chemical that may release formaldehyde vapours, which can cause serious health effects. Exposure may cause respiratory irritation, allergic skin reactions, and serious eye irritation. Formaldehyde released from Paraformaldehyde is classified as a carcinogen and may cause cancer. Avoid inhalation of dust and vapours and prevent direct contact with the eyes and skin. Handle in a properly functioning chemical fume hood using suitable chemical-resistant gloves, safety goggles, and appropriate protective laboratory clothing. Keep containers tightly closed when not in use and minimise dust generation. Store in a cool, dry, well-ventilated area away from incompatible substances and sources of ignition. Follow the supplier's Safety Data Sheet (SDS) for proper handling, storage, exposure control, and disposal.
