Hanus Solution for Determination of Iodine Number is a standardized solution used in analytical and pharmaceutical laboratories to determine the iodine number of fats, oils, and unsaturated compounds, providing a measure of unsaturation and quality in lipid-based materials.
🏭⚗️ Production
Hanus Solution is prepared by dissolving iodine monochloride (ICl) in glacial acetic acid under controlled conditions to achieve the precise concentration required for accurate determination of iodine number. The solution is carefully standardized against a primary standard, such as sodium thiosulphate, to ensure consistency and reliability in titrimetric analyses. It is stored in tightly sealed, light-resistant containers to prevent decomposition and maintain long-term stability.
🔬 Properties
The solution is a reddish-brown, clear liquid with strong oxidizing properties. It is highly reactive with unsaturated compounds and remains stable under normal laboratory conditions if protected from light and moisture. Exposure to air, light, or impurities can lead to gradual degradation, affecting its reactivity.
🧪 Applications
Hanus Solution is primarily employed in the determination of iodine number in fats, oils, and waxes, which is essential for quality control, formulation, and purity assessment in pharmaceutical and food industries. It is used in titrimetric analyses to quantify unsaturation and to evaluate the oxidative stability of lipid-based formulations.
⚠️ Safety
Hanus Solution is corrosive and a strong oxidizing agent. Contact with skin or eyes can cause severe irritation or burns. Appropriate protective equipment such as gloves, goggles, and lab coats should be worn during handling. The solution should be stored in a cool, dark place away from reducing agents and combustible materials. Disposal must follow laboratory safety protocols and local environmental regulations.
