Mercurous iodide is an inorganic compound with the chemical formula HgI2. It has two variants. One is red mercurous iodide, a tetragonal crystal, with a density of 6.36 g/cm3 (at 25℃). It turns yellow at 127℃ and reverts to red upon cooling. The other is yellow mercurous iodide, an orthorhombic crystal, with a density of 6.094 g/cm3 (at 127℃), a melting point of 259℃, and a boiling point of 354℃. It is unstable at room temperature and transforms into the stable red variant after a few hours. It is insoluble in water but soluble in methanol, ethanol, ether, chloroform, glycerol, acetone, dithiocarbonane, and sodium thiosulfate solution. It is used in medicine and as a chemical reagent. Mercurous iodide exists in nature in the form of the extremely rare iodine-mercury ore (Coccinite).

1. Prepare Nesseler's reagent and Mayer's reagent, and determine palladium.
2. In analytical chemistry, Nesseler's reagent and Mayer's alkaloid reagent are used to prepare for the qualitative detection of ammonium ions and ammonia.
3. Be used as semiconductor materials.
4. Be used in gamma ray or X-ray detection or imaging equipment operating at room temperature.
5. In medicine, mercury iodide is used to treat syphilis. In veterinary medicine, mercury iodide is contained in ointments for treating bone spurs and enlarged mucous cysts.

Emergency response: Isolate the contaminated area, restrict access. Cut off the source of fire. It is recommended that emergency responders wear self-contained breathing apparatus and protective suits. Do not directly contact the leaked substance. For small-scale leakage: Avoid dust generation, collect the leaked substance with clean shovels in dry, clean, and covered containers. For large-scale leakage: Cover with plastic sheeting or canvas to reduce dispersion. Then collect, recycle or transport to a waste disposal site for disposal. Personal protection: Respiratory protection: Workers should wear head-covering type electrically powered supplied-air filtering dust masks. In case of necessity, wear isolated breathing apparatus. Eye protection: Protection in respiratory protection has already been provided. Physical protection: Wear coverall rubber-taped protective clothing. Hand protection: Wear rubber gloves. Other: Prohibit smoking, eating and drinking at the work site. After work, take a shower and change clothes. Store contaminated clothes separately and keep them ready for washing. Maintain good hygiene habits. First aid measures: Skin contact: Immediately remove contaminated clothing, rinse with plenty of flowing water for at least 15 minutes. Seek medical attention. Eye contact: Immediately lift the eyelids and rinse with plenty of flowing water or physiological saline for at least 15 minutes. Seek medical attention. Inhalation: Quickly evacuate to an area with fresh air. Keep the respiratory tract unobstructed. If breathing difficulties occur, administer oxygen inhalation. If breathing stops, perform artificial respiration immediately. Seek medical attention. Ingestion: Induce vomiting. Wash the stomach with water or 2% sodium bicarbonate solution (avoid using physiological saline). Give milk or egg white for drinking. Seek medical attention.

Storage Method: Store in a dedicated warehouse that is cool and well-ventilated, and implement the system of "double-person receiving and dispatch, double-person custody". Keep away from fire sources and heat sources. Avoid exposure to light. Seal the packaging. Store separately from oxidants, edible chemicals, and avoid mixing them. Avoid contact with bromides, chlorides, ammonia, alkalis, cyanides, copper salts, lead salts, iodoform, and hydrogen peroxide. Appropriate materials should be available to contain the leakage at the storage area.
Transportation Method: Before transportation, check whether the packaging containers are intact and sealed. During transportation, ensure that the containers do not leak, collapse, fall, or damage. Strictly prohibit mixed transportation with acids, oxidants, food, and food additives. The transportation vehicles should be equipped with emergency handling equipment for leakage. During transportation, prevent exposure to sunlight, rain, and high temperatures.
