Paraformaldehyde - Wikipedia
Paraformaldehyde (PFA) is the smallest polyoxymethylene, the polymerization product of formaldehyde with a typical degree of polymerization of 8–100 units. Paraformaldehyde commonly has a slight odor of formaldehyde due to decomposition. Paraformaldehyde is a …
Paraformaldehyde powder, 95 30525-89-4 - MilliporeSigma
Paraformaldehyde is the polymeric form of formaldehyde. It is a solid. Formaldehyde is a gas which when dissolved in water gives a formaldehyde solution. Commercially available formaldehyde solutions usually contain 10-15% methanol, which prevents the formaldehyde from forming the polymeric paraformaldehyde.
Paraformaldehyde - PubChem
Description. Paraformaldehyde appears as a white solid with a light pungent odor. A linear polymer of formaldehyde of formula HO (CH2-O)xH where x averages about 30. Soluble in water when x is less than 12; higher polymers are not immediately soluble. Slow dissolution in water proceeds by means of hydrolysis to give fragments of lower x.

Paraformaldehyde (PFA) is the smallest polyoxymethylene, the polymerization product of formaldehyde with a typical degree of polymerization of 8–100 units. Paraformaldehyde commonly has a slight odor of formaldehyde due to decomposition. Paraformaldehyde is a poly-acetal.
Paraformaldehyde is a white crystalline powder of polymerized formaldehyde, a flammable solid that can emit formaldehyde gas when heated or mixed with water. Many laboratories at UW use formalin solutions and paraformaldehyde solutions or solids as part of their research and clinical activities.
Paraformaldehyde - an overview | ScienceDirect Topics
Paraformaldehyde is a fixative commonly used in staining membrane-associated proteins. It chemically crosslinks free amino groups, preserving cellular architecture by establishing a network of interactions.
4% Paraformaldehyde (PFA) solution preparation - Sharebiology

Making Paraformaldehyde Solution. 4% paraformaldehyde is usually made in PBS or TBS at 70 °C with several drops of 5N NaOH to help clarify the solution. Prepare 4% paraformaldehyde solution in a chemical hood if you don’t want to be slightly fixed yourself.
Formaldehyde vs. Paraformaldehyde - What's the Difference?
Formaldehyde is widely used in the production of resins, plastics, and textiles, as well as in disinfection and embalming processes. On the other hand, paraformaldehyde serves as a convenient source of formaldehyde gas and finds applications in adhesives, coatings, and pharmaceutical synthesis.
