Magnesium;carbanide;bromide

Magnesium carbanide bromide (CH3BrMg) is an organometallic compound with CAS number 75-16-1 and molecular weight 119.24 g/mol. This substance represents a Grignard reagent, specifically methylmagnesium bromide, which is formed by the reaction of magnesium metal with methyl bromide in anhydrous ether. It appears as a solution and is highly reactive with water and moisture, making it an important intermediate in organic synthesis for forming carbon-carbon bonds.

Magnesium carbanide bromide exists as a solution in anhydrous ether or THF at room temperature. The compound is extremely moisture-sensitive and reacts violently with water, producing methane gas and magnesium hydroxide. It has a molecular formula of CH3BrMg with a molar mass of 119.24 g/mol. The solution is typically colorless to pale yellow and must be kept under inert atmosphere due to its high reactivity with air and moisture.

Magnesium carbanide bromide serves as a crucial Grignard reagent in organic synthesis for pharmaceutical, agrochemical, and fine chemical manufacturing. It enables the formation of carbon-carbon bonds by reacting with carbonyl compounds, nitriles, and other electrophiles to produce alcohols, ketones, and carboxylic acids. The compound is extensively used in research laboratories and industrial processes for synthesizing complex organic molecules, making it indispensable in modern organic chemistry applications.

Magnesium carbanide bromide requires handling under strict anhydrous conditions using inert gas atmosphere (nitrogen or argon). Essential PPE includes chemical-resistant gloves, safety goggles, and lab coat. Work must be conducted in a well-ventilated fume hood away from water sources and moisture. Use dry glassware and syringes for transfer operations. Keep fire extinguishing equipment nearby as the compound can generate flammable gases. Never allow contact with water or alcohols during handling procedures.

Magnesium carbanide bromide must be stored under inert atmosphere in tightly sealed containers at temperatures between 2-8°C. Keep containers away from moisture, water, alcohols, and acids which are incompatible and cause violent reactions. Store in a dry, well-ventilated area away from heat sources and ignition. Use amber glass bottles or steel containers suitable for air-sensitive materials. Regular integrity checks of sealing systems are essential to prevent moisture ingress and degradation.

Magnesium carbanide bromide contact requires immediate action due to its caustic nature. For skin contact, brush off any solid material and flush with copious amounts of water for 15 minutes while removing contaminated clothing. For eye contact, rinse immediately with water for 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. Never use water directly on spilled material as it causes violent reaction. Seek immediate medical attention for all exposure incidents.

Magnesium carbanide bromide disposal requires careful quenching with isopropanol or careful addition to ice-cold water under controlled conditions to prevent violent reactions. The resulting aqueous solution can then be neutralized and disposed of according to local environmental regulations. Never dispose of unreacted material directly into drains or environment. Contact specialized chemical waste disposal companies familiar with organometallic compounds. Follow all applicable national and EU waste disposal regulations for hazardous chemical substances.

Magnesium carbanide bromide is classified under ADR Class 4.3 (substances which emit flammable gases in contact with water), Packing Group I, indicating high danger level. Transport requires specialized packaging that prevents moisture ingress and meets UN specification standards. Vehicles must carry appropriate placarding and emergency response information. Shipments require dangerous goods documentation and trained personnel. The compound cannot be transported by air due to its reactive nature and must use road/rail transport under strict ADR compliance.

Magnesium carbanide bromide falls under REACH regulation requiring registration for quantities above one tonne per year. The substance is not classified as SVHC (Substance of Very High Concern) under current EU regulations. However, its reactive nature means it must comply with workplace safety regulations and proper risk assessments. Users must maintain safety data sheets and follow occupational exposure limits. Transport is regulated under ADR Class 4.3 requirements for water-reactive substances.
