Paraformaldehyde is a polymeric form of formaldehyde, widely recognized for its diverse industrial and laboratory applications. Chemically, it is a white crystalline solid with the chemical formula (CH2O)n, where "n" represents the degree of polymerization. One of the essential characteristics of paraformaldehyde is its molecular weight, which varies depending on the polymer length but typically centers around 30 to 1000 g/mol. This molecular variability influences its reactivity and solubility in water, making it a versatile compound. The CAS number assigned to paraformaldehyde is 30525-89-4, a key reference point used globally for identification and regulatory purposes. Understanding its molecular weight and CAS number ensures accurate handling and application across industries. Its ability to depolymerize back into formaldehyde upon heating makes it particularly valuable as a formaldehyde source in chemical synthesis and biological fixation.

Paraformaldehyde's physical form as a powder or granules enhances its storage stability compared to gaseous formaldehyde solutions. This stability is critical for industries requiring long shelf-lives and consistent performance. The compound functions effectively as a fixative in biological and medical laboratories, preserving tissue and cellular structures by cross-linking proteins and nucleic acids. This fixative property is foundational for histology, pathology, and microscopy, making paraformaldehyde indispensable for scientific research and diagnostics. Moreover, its industrial applications extend to resin production, adhesives, and disinfectants, where controlled formaldehyde release is required.

Paraformaldehyde serves multiple roles across several key industries, highlighting its importance beyond laboratory usage. In the chemical manufacturing sector, it acts as a formaldehyde donor in producing phenolic resins, urea-formaldehyde resins, and melamine resins, which are vital for plywood, particleboard, and molding compounds. These resins impart strength, durability, and resistance to moisture, heat, and chemicals, underscoring paraformaldehyde's contribution to building materials and automotive components.

The agricultural industry utilizes paraformaldehyde as a fumigant and disinfectant, effectively controlling pests, fungi, and bacteria in soil and storage facilities. This application ensures higher crop yields and food safety, aligning with sustainable farming practices. In healthcare and research, paraformaldehyde fixative solutions stabilize biological samples, preserving cellular morphology and enabling detailed microscopic examination. This capability is critical for disease diagnosis, vaccine development, and forensic studies.

Environmental technology also benefits from paraformaldehyde through its use in water treatment processes, where it helps control microbial contamination. The compound’s versatility, combined with its controlled release of formaldehyde, enables safer and more efficient chemical processes. Across all these industries, the demand for high-purity paraformaldehyde with consistent molecular weight and performance is paramount, driving manufacturers like HUTIBI RUIYUANTONG CHEMICAL CO.,LTD to uphold stringent quality standards.
