1. Basic Information and Parameters

Our product, High Quality Paraformaldehyde with CAS number 30525 - 89 - 4, is well - known for its high purity and low price. Paraformaldehyde is a white crystalline powder with a characteristic formaldehyde odor. It is a polymer of formaldehyde, with the chemical formula (CH₂O)ₙ, where n typically ranges from 8 to 100.

The melting point of our paraformaldehyde is around 120 - 170°C, and it starts to decompose into formaldehyde gas at elevated temperatures. It has a density of approximately 1.4 g/cm³. Our product meets strict quality control standards, ensuring a high degree of purity, which makes it suitable for a wide range of applications.

2. Uses of the Product

Paraformaldehyde has numerous applications across different industries. In the chemical industry, it is mainly used as a source of formaldehyde. Formaldehyde is a key raw material for the production of various resins, such as phenolic resins, urea - formaldehyde resins, and melamine - formaldehyde resins. These resins are widely used in the manufacturing of plywood, particleboard, and other wood - based panels, as well as in the production of plastics, adhesives, and coatings.

In the medical and pharmaceutical fields, paraformaldehyde is used as a fixative for biological specimens. It helps to preserve the structure and morphology of cells and tissues, enabling accurate histological and pathological examinations. In addition, it can be used as a disinfectant due to its antibacterial and antifungal properties.

In the agricultural sector, paraformaldehyde can be used as a soil fumigant to control nematodes, fungi, and other soil - borne pests.

3. How to Use the Product

When using paraformaldehyde, it is essential to follow strict safety procedures. It should be handled in a well - ventilated area, preferably under a fume hood, as it can release formaldehyde gas, which is a toxic and carcinogenic substance. Protective equipment, such as gloves, goggles, and a respirator, should be worn.

To dissolve paraformaldehyde, it is usually heated in an appropriate solvent, such as water or buffer solutions. The heating process should be carried out slowly and carefully to avoid over - heating and excessive release of formaldehyde. The concentration of the solution depends on the specific application. For example, for tissue fixation, a 4% paraformaldehyde solution in phosphate - buffered saline (PBS) is commonly used.

4. Detailed Usage Case Studies

Case 1: Wood - based Panel Manufacturing
A wood - based panel factory used our paraformaldehyde to produce phenolic resins. By using our high - quality paraformaldehyde, they were able to achieve a more stable resin synthesis process. The resulting phenolic resins had excellent bonding strength, which improved the quality of the plywood and particleboard produced. The low price of our product also helped the factory to reduce production costs, increasing their competitiveness in the market.

Case 2: Medical Research
A medical research institute used our paraformaldehyde for tissue fixation in their histological studies. They prepared a 4% paraformaldehyde solution in PBS according to the standard protocol. The fixed tissues showed well - preserved cellular structures, which allowed for accurate microscopic examination. The high purity of our paraformaldehyde ensured minimal background interference, enabling clear and reliable research results.
