Paraformaldehyde (PFA) is the smallest polyoxymethylene. It is polymerization product of formaldehyde.
Paraformaldehyde has been used in the past for disinfecting sickrooms, clothing, linen and sickroom utensils. It has been used as a fumigant and in manufacturing synthetic resins & as a fixative in electron microscopy. Used in the preparation of formalin fixatives for tissues or cells when the samples are to be used in florescence studies.
