Pentachloro-lambda5-phosphane

Pentachloro-lambda5-phosphane is an inorganic phosphorus compound with the molecular formula Cl5P and CAS number 10026-13-8. It has a molecular weight of 208.2 g/mol and belongs to the family of phosphorus pentahalides. This chemical compound is classified as highly hazardous, exhibiting acute toxicity, skin corrosivity, and specific target organ toxicity properties. It requires careful handling due to its dangerous nature and corrosive characteristics.

Pentachloro-lambda5-phosphane is a phosphorus pentachloride compound that typically appears as a yellowish-white crystalline solid at room temperature. It has a pungent, irritating odor and readily hydrolyzes in the presence of moisture, releasing hydrogen chloride gas. The compound has a molecular weight of 208.2 g/mol and decomposes when exposed to water or humid conditions, making it highly reactive with aqueous environments.

Pentachloro-lambda5-phosphane is primarily used as a chlorinating agent in organic synthesis and pharmaceutical manufacturing. It serves as a reagent for converting alcohols to alkyl chlorides and carboxylic acids to acid chlorides. The compound is also utilized in the production of organophosphorus compounds and as an intermediate in various chemical processes. Its applications are mainly restricted to industrial and laboratory settings due to its hazardous properties.

Pentachloro-lambda5-phosphane requires strict safety measures during handling due to its corrosive and toxic nature. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, face shield, and protective clothing. Work must be conducted in a well-ventilated area or under a fume hood to prevent inhalation exposure. Avoid contact with skin, eyes, and clothing, and ensure emergency eyewash and safety shower facilities are readily accessible nearby.

Pentachloro-lambda5-phosphane must be stored in a cool, dry place away from moisture and humidity to prevent decomposition. The container should be tightly sealed and kept in a well-ventilated area, separated from incompatible materials such as water, alcohols, and bases. Storage areas should be equipped with appropriate spill containment measures and maintained at stable temperatures. Regular inspection of containers for signs of corrosion or leakage is essential.

Immediate action is required for any contact with pentachloro-lambda5-phosphane due to its corrosive properties. For skin contact, immediately flush the affected area with copious amounts of water for at least 15 minutes while removing contaminated clothing. In case of eye contact, rinse thoroughly with water and seek immediate medical attention. If inhaled, move the person to fresh air and provide oxygen if breathing is difficult. Always seek medical assistance promptly.

Pentachloro-lambda5-phosphane must be disposed of as hazardous chemical waste according to local and European regulations. The compound cannot be discharged into sewers or waterways due to its corrosive and toxic nature. Disposal should be conducted through licensed hazardous waste management companies that can handle corrosive materials. Small quantities may be neutralized by qualified professionals before disposal, but this should never be attempted without proper expertise and equipment.

Pentachloro-lambda5-phosphane is classified under ADR Class 8 (corrosive substances) with Packing Group II, indicating high danger level for transport. It requires specialized packaging meeting UN specifications and proper hazard labeling including corrosive substance markings. Transportation must comply with ADR regulations for dangerous goods, including driver certification and vehicle equipment requirements. Proper documentation and emergency response information must accompany all shipments.

Pentachloro-lambda5-phosphane is subject to various European chemical regulations including REACH registration requirements and CLP classification obligations. The compound is classified with multiple hazard classes (Acute Tox. 2, Acute Tox. 4, STOT RE 2, Skin Corr. 1B) requiring specific labeling and safety data sheets. While not currently listed as an SVHC substance, it may be subject to additional restrictions depending on intended use and local regulations.

Pentachloro-lambda5-phosphane is available through OYSI, a specialized European distributor of technical chemicals and laboratory reagents. As an established chemical supplier, OYSI can provide this regulated substance to qualified industrial and research customers with appropriate handling capabilities. Due to the hazardous nature of this compound, purchases typically require verification of proper storage facilities, safety protocols, and legitimate industrial or research applications before order processing.
