Versatile Applications in Industry and Research

Paraformaldehyde plays a crucial role across multiple sectors, including pharmaceuticals, disinfectants, and microscopy as a reliable fixative. Owing to its chemical stability and efficacy, it finds use in both industrial processes and specialized laboratory environments. Its recognized standards ensure suitability for medical, laboratory, and industrial-grade requirements.

Safe and Effective Handling

Stored in a cool, dry place with tightly closed containers, paraformaldehyde maintains its integrity and shelf life. Users must exercise caution, as it is toxic by inhalation and skin contact. Proper safety measures, including the use of protective equipment and ventilation, are essential to mitigate exposure risks during handling and storage.

FAQs of Paraformaldehyde:

Q: How should paraformaldehyde be stored to ensure maximum stability?

A: Paraformaldehyde should be kept in a cool, dry place with the container tightly sealed to maintain its stability and extend its 12-month shelf life.

Q: What are the main uses of paraformaldehyde in medical and industrial contexts?

A: Paraformaldehyde is mainly used as a disinfectant, a component in pharmaceutical production, and as a fixative in microscopy for preserving specimen structure.

Q: When does paraformaldehyde begin to decompose, and what happens during decomposition?

A: Paraformaldehyde decomposes before boiling, particularly upon heating, releasing formaldehyde gas, which requires precautionary handling due to its toxicity.

Q: Where is paraformaldehyde typically sourced or supplied from?

A: Paraformaldehyde is distributed, exported, and supplied by manufacturers and traders in India, typically packaged in bags or drums to meet industrial and laboratory specifications.

Q: What is the process for using paraformaldehyde in laboratory applications?

A: For laboratory use, paraformaldehyde is often dissolved in water or appropriate solvents to prepare fixative solutions for tissue preservation or microscopic analysis.

Q: What are the safety benefits of proper paraformaldehyde handling and storage?

A: Proper handling and storage minimize exposure to toxic fumes and reduce the risk of accidents, ensuring worker safety and maintaining chemical efficacy for its intended applications.
