General description
Paraformaldehyde is also referred as polyoxymethylene. It participates as an external CO source in the synthesis of aromatic aldehydes and esters.
Application
Paraformaldehyde can be used as a:
- Methylene building block in the Mannich reaction with primary amines and alkynes to synthesize propargyl amines.
- Hydroxymethylation reagent to synthesize homoallylic alcohols by reacting with 1,1-disubstituted allenes.
- Formylation reagent in the Ir-catalyzed N-formylation of amines to synthesize formamides.

The objective of this study was to find a simple method to preserve cells for subsequent flow cytometry (FACS) analysis. We determined that fixation in 1% paraformaldehyde-0.85% saline solution did not significantly alter the Coulter volume, light scatter of fluorescence
