Tetraphenylphosphonium Chloride CAS 2001-45-8

1. Tetraphenylphosphonium chloride is a quaternary phosphonium salt primarily used as a phase transfer catalyst in organic synthesis to facilitate reactions between immiscible phases, including alkylations, esterifications, and nucleophilic substitutions .
2. Tetraphenylphosphonium chloride CAS 2001-45-8 serves as a selective precipitant for the removal of metal ions such as mercury, cadmium, and arsenic from industrial wastewater and analytical samples .
3. Tetraphenylphosphonium chloride is employed as a membrane potential probe in biological research to study mitochondrial membrane potential and cellular bioenergetics .
4. In materials science, tetraphenylphosphonium chloride is used as a template in the synthesis of zeolites and mesoporous materials, and as an electrolyte additive in electrochemical applications .

1. Tetraphenylphosphonium chloride must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture; recommended storage at room temperature in a cool, dark place .
2. Tetraphenylphosphonium chloride CAS 2001-45-8 is classified with GHS hazard statements H302 (Harmful if swallowed), H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation), with signal word "Warning" .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas .
4. Keep away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases to prevent decomposition; wash thoroughly after handling .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when Tetraphenylphosphonium chloride is released .
2. Collect Tetraphenylphosphonium chloride CAS 2001-45-8 by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent the product from entering drains or water courses .
4. Dispose of collected material according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. Tetraphenylphosphonium chloride is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, and phosphorus oxides .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as Tetraphenylphosphonium chloride CAS 2001-45-8 may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Tetraphenylphosphonium chloride due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
