Paraformaldehyde is a polymer of formaldehyde, commonly used as a disinfectant, preservative, and reagent in laboratories, histology, and industrial applications. It releases formaldehyde gas upon heating, making it useful for sterilization, embalming, and chemical synthesis. Paraformaldehyde has a CAS number of 30525-89-4, with a molecular formula of HO(CH2O)nH and a repeating unit molecular weight of approximately 30.03. It must be stored between 2 to 8°C and carries a **Danger** signal word due to its hazardous properties. Molekula supplies paraformaldehyde from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
