Iodine resublimed
Product Overview & Quality
- Product Name: Iodine resublimed
- Brand: Kemaus (Product Code: KA-267)
- Grade: Analytical Reagent (AR Grade). Purified via repeated thermal resublimation cycles under strict Kemaus laboratory protocols to completely eliminate trace chloride, bromide, and organic contaminants, ensuring maximum chemical reliability.
- Physical Properties: Heavy, bluish-black to dark grey crystalline flakes with a metallic luster and a sharp, characteristic pungent odor. It readily undergoes sublimation at room temperature, releasing a dense, volatile violet vapor directly from its solid state.
- Solubility: Extremely slightly soluble in water; highly soluble in aqueous potassium iodide solutions and organic solvents like alcohol, ether, and chloroform.
- Key Use: Heavily utilized to prepare standard iodine volumetric titrants for iodimetric redox titrations (such as analyzing Vitamin C levels or fat iodine values). Functions as the benchmark reagent for starch detection assays in biochemistry and botany labs (producing a distinct deep-blue complex). Commonly applied in thin-layer chromatography (TLC) as a chemical visualization agent via iodine vapor chambers, and used as a major intermediate in specialized organic synthesis.
Safety & Hazards (Critical)
- Classification: Harmful if swallowed or inhaled. Causes severe skin burns and serious eye damage. May cause damage to organs (Thyroid) through prolonged or repeated exposure.
- Health Risks: Iodine vapors are highly corrosive and destructive to the eyes and upper respiratory tract, causing severe tearing, coughing, and breathing difficulties. Direct skin contact causes chemical burns and leaves intense, stubborn brown stains on biological tissues.
- Environmental Hazards: Very toxic to aquatic life. Strict hazardous chemical disposal protocols apply.
- First Aid Measures: Immediately flush affected eyes or skin with plenty of flowing water for at least 15 minutes. If inhaled, move the victim to fresh air immediately. Seek urgent medical evaluation.
Handling & Storage
- Storage: Volatile and Corrosive. Escaping iodine vapors aggressively attack rubber, plastic seals, and metal storage shelves. Must be stored in its original, tightly sealed Kemaus amber glass container with an intact inner cap. Keep in a cool, dry, and well-ventilated dedicated chemical safety cabinet at room temperature (below 30 degrees Celsius). Keep strictly away from strong reducing agents, ammonia, metal powders, and direct heat sources.
- Precautions: Comprehensive PPE is mandatory, including chemical-resistant laboratory gloves, safety goggles, and an acid-gas chemical respirator. Handle strictly within a functioning fume hood to avoid direct exposure to its toxic, subliming violet vapors.
