Paraformaldehyde is a polymer of formaldehyde with the chemical formula (CH2O)n, where n is typically in the range of 8 to 100. It is a white, crystalline solid composed of small, polymeric formaldehyde units. Paraformaldehyde is commonly used as a solid form of formaldehyde, and it has various applications in different fields.
Form and Structure:
Paraformaldehyde is a low-molecular-weight polymer of formaldehyde, consisting of repeating CH2O units.
It is often produced in the form of white, crystalline granules or as a powder.
Uses:
Fixative in Histology: Paraformaldehyde is commonly used in histology and pathology laboratories as a fixative for preserving biological specimens for microscopic analysis.
Disinfectant: It has disinfectant properties and can be used for sterilizing equipment.
Crosslinking Agent: Paraformaldehyde is used in the crosslinking of proteins, peptides, and nucleic acids in molecular biology applications.
Chemical Synthesis: It serves as a source of formaldehyde in various chemical reactions and syntheses.
Handling and Safety:
Paraformaldehyde should be handled with care, and precautions should be taken to avoid inhalation, skin contact, or ingestion.
When paraformaldehyde is heated, it releases formaldehyde gas, which is a strong irritant. Adequate ventilation and protective equipment should be used when working with paraformaldehyde.
Dissolution:
To use paraformaldehyde as a fixative or in other applications, it is typically dissolved in water to generate a formaldehyde solution.
Storage:
Paraformaldehyde should be stored in a cool, dry place away from heat sources and incompatible materials.

Sodium metabisulfite is white or yellow crystalline powder or small crystal, with a strong SO2 odor, soluble in water, the aqueous solution is acidic, when contacted with strong acid, SO2 is released to form corresponding salts, and it is oxidized to Na2S2O6 when placed in the air for a long time. Therefore, the product cannot be stored for a long time. Above 150 degrees Celsius, SO2 is decomposed.
