ACGIH: TWA 0.01 mg/m3; TWA 0.002 mg/m3
NIOSH: IDLH 9 mg/m3 | [Uses]
Made by heating cadmium to redness in bromine vapor. The
yellowish crystalline powder is soluble in water and alcohol
and is slightly soluble in ether. The crystals are deliquescent
and must be kept in a well-stoppered bottle. Like its iodide
counterpart, cadmium bromide was used in collodion in
conjunction with an iodide of either ammonium or potassium. | [CAS DataBase Reference]

| Hazard Information | Back Directory | [General Description]
Odorless white solid. Mixes with water. | [Reactivity Profile]
CADMIUM BROMIDE(7789-42-6) has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive. | [Air & Water Reactions]
Water soluble. | [Health Hazard]
Inhalation causes coughing, sneezing, symptoms of lung damage. Ingestion produces severe toxic symptoms; both kidney and liver injuries may occur. Contact with eyes causes irritation. | [Potential Exposure]
Cadmium bromide is used in photography, engraving, and lithography | [Fire Hazard]
Special Hazards of Combustion Products: Toxic cadmium oxide fumes may form in fires. | [First aid]
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact,
avoid spreading material on unaffected skin. Keep victim
warm and quiet. Effects of exposure (inhalation, ingestion,
or skin contact) to substance may be delayed. Ensure that
medical personnel are aware of the material(s) involved
and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing
overexposure, as pulmonary edema may be delayed. As
first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. | [Shipping]

Required | [Description]
admium bromide is a white to yellowishcrystalline powder. Molecular weight=272.22; BoilingCadmium bromide 505point=863℃; Freezing/Melting point=567℃. HazardIdentification (based on NFPA-704 M Rating System):Health 3, Flammability 0, Reactivity 0. Soluble in water. | [Chemical Properties]
Cadmium bromide is a white to yellowish
crystalline powder. | [Chemical Properties]
White to yellowish crysatlline powder | [Physical properties]
White to yellowish powder or flakes; hexagonal crystal system; hygroscopic; density 5.192g/cm3; melts at 568°C; vaporizes at 844°C; soluble in water, alcohol, ether, acetone, and liquid ammonia. | [Preparation]
Cadmium bromide is prepared by heating cadmium with bromine vapor. Also the compound can be prepared by the treatment of dry cadmium acetate with glacial acetic acid and acetyl bromide. Alternatively, it may be obtained by dissolving cadmium or cadmium oxide in hydrobromic acid and evaporating the solution to dryness under helium in an inert atmosphere. | [storage]
Color Code—Blue: Health Hazard: Store in asecure poison location. Prior to working with cadmiumbromide you should be trained on its proper handling andstorage. Cadmium bromide must be stored to avoid contactwith Potassium, since violent reactions occur. A regulated,marked area should be established where this chemical ishandled, used, or stored in compliance with OSHAStandard 1910.1045. | [Purification Methods]
Crystallise it from water (0.6mL/g) between 100o and 0o, and dry it at 110o. It forms the monohydrate below 36o and the tetrahydrate above 36o. [Wagenknecht & Juza in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1096 1965.] |
