Product Description

Polymeric Aldehyde The solubility and rate of solution of paraformaldehyde in water are greatly influenced by pH and temperature. High-Grade Chemicals Both acidic and alkaline pHs and higher temperatures accelerate the rate of solution. Once dissolved, the paraform solution behaves like the methanol-free Formaldehyde Solution of the same concentration. High-End Chemicals Paraformaldehyde is composed of varying molecular weight polymers of polyoxymethylene glycols. High Purity Chemicals It is generally prepared as 91 or 95% Formaldehyde by weight with the remainder being free and combined water. The combined water is the terminating agent for the paraformaldehyde chains. Paraformaldehyde reacts chemically as formaldehyde at a rate determined by its rate of depolymerization under the conditions of use. The rate of depolymerization and thus perceived reactivity decreases with increasing molecular weight of the polymer chains. Industry Chemicals


Paraformaldehyde CAS 30525-89-4 is not a fixative; it must be depolymerized to formaldehyde in solution. In cell culture, a typical formaldehyde fixing procedure would involve using a 4% formaldehyde solution in phosphate buffered sline (PBS) on ice for 10 minutes.
