Formaldehyde Solution 20% is a concentrated aqueous aldehyde solution used in laboratory environments for fixation, preservation, and controlled chemical reactions, providing strong cross-linking capability and reliable performance in analytical and biological workflows.
🏭⚗️ Production
Prepared under tightly regulated industrial conditions to ensure accurate aldehyde concentration, low methanol-stabilizer variability, and controlled impurity levels. Each batch undergoes quality assessment for assay consistency, pH stability, clarity, and absence of particulate contamination. Packaged in airtight, chemical-resistant containers to minimize vapor release and prevent degradation during storage and handling.
🔬 Properties
A clear, colorless liquid with a sharp, pungent odor, exhibiting strong reactivity and protein-crosslinking capability. Miscible with water and sensitive to temperature and light, with potential to release formaldehyde vapors over time. Chemically stable under recommended storage conditions. Volatile and reactive toward oxidizing agents; store in sealed containers in a cool, well-ventilated area, protected from heat and ignition sources.
🧪 Applications
Used as a tissue fixative and preservative in histology and laboratory workflows requiring controlled cross-linking activity. Suitable for sample stabilization, morphological preservation, and certain analytical procedures where consistent aldehyde reactivity is required. Employed in regulated laboratory environments following strict safety and handling protocols due to its hazardous nature.
⚠️ Safety
Toxic and potentially carcinogenic. Causes severe irritation to eyes, skin, and respiratory tract; inhalation of vapors may be harmful. Liquid and vapor can provoke allergic skin or respiratory reactions. Handle only in well-ventilated areas or under fume hoods using proper PPE, including gloves, lab coat, and eye protection. Store securely in tightly closed containers away from incompatible materials and sources of heat.
