Pentachloromolybdenum

Pentachloromolybdenum is an inorganic compound with the molecular formula Cl5Mo and CAS number 10241-05-1. This molybdenum chloride consists of a molybdenum atom bonded to five chlorine atoms, forming a dark-colored crystalline solid. With a molecular weight of 273.2 g/mol, it serves as an important molybdenum source in various chemical applications and synthesis processes.

Pentachloromolybdenum is a dark crystalline solid that appears as black or dark brown crystals. It is highly hygroscopic and readily decomposes in the presence of moisture, forming hydrogen chloride gas. The compound is soluble in organic solvents and reacts vigorously with water. It has a high melting point and exhibits strong oxidizing properties due to the high oxidation state of molybdenum.

Pentachloromolybdenum is primarily used as a precursor in the synthesis of molybdenum-based catalysts and organometallic compounds. It serves as a starting material for preparing molybdenum complexes used in chemical research and industrial catalysis. The compound is also utilized in the production of specialized molybdenum materials and as a reagent in advanced chemical synthesis processes requiring high-purity molybdenum sources.

Pentachloromolybdenum requires careful handling using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in a well-ventilated area or under a fume hood to prevent inhalation of any released vapors. Avoid contact with moisture and water, as this can lead to decomposition and release of corrosive hydrogen chloride gas.

Pentachloromolybdenum must be stored in tightly sealed, moisture-proof containers in a cool, dry environment away from any sources of humidity. The storage area should be well-ventilated and separated from incompatible materials such as water, alcohols, and reducing agents. Keep containers in a designated chemical storage area with appropriate labeling and ensure protection from direct sunlight and temperature fluctuations.

In case of skin contact with pentachloromolybdenum, immediately remove contaminated clothing and flush the affected area with plenty of water for at least 15 minutes. For eye contact, rinse thoroughly with water and seek immediate medical attention. If inhaled, move to fresh air immediately. Do not induce vomiting if ingested and seek medical attention promptly while providing the safety data sheet to medical personnel.

Pentachloromolybdenum must be disposed of as hazardous chemical waste through licensed waste management companies in accordance with local and European waste regulations. Never dispose of this compound in regular waste streams or pour down drains. Collect waste in appropriate containers, label clearly, and arrange for professional hazardous waste collection. Consult local environmental authorities for specific disposal requirements and approved waste handlers.

Pentachloromolybdenum is classified as ADR Class 8 (Corrosive substances), Packing Group III for transportation purposes. It must be packaged in approved containers that meet UN specification requirements for corrosive materials. Proper shipping documentation, labeling with Class 8 hazard labels, and compliance with ADR regulations are mandatory. Transportation should be handled by carriers certified for hazardous materials transport.

Pentachloromolybdenum is subject to standard chemical regulations under REACH and CLP in Europe, requiring proper registration, classification, and safety data sheet provision. It is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with workplace safety regulations, proper labeling requirements, and maintain appropriate safety documentation. Industrial users should ensure compliance with local occupational health and safety standards.
