Tetraethylammonium Chloride CAS 56-34-8

1. Tetraethylammonium chloride CAS 56-34-8 is primarily used in pharmacological and physiological research as a selective potassium channel blocker to study nerve and muscle function .
2. Tetraethylammonium Chloride serves as a source of tetraethylammonium ions in organic chemical synthesis, for example, as a phase transfer catalyst or electrolyte .
3. Applications of Tetraethylammonium chloride also include its use in electrochemical analysis and as a general laboratory reagent .

1. Store Tetraethylammonium chloride CAS 56-34-8 in a tightly sealed container under an inert atmosphere (e.g., argon) in a cool, dry, and well-ventilated place, as it is hygroscopic and moisture-sensitive .
2. Keep Tetraethylammonium chloride away from strong oxidizing agents, heat, and moisture to prevent hazardous decomposition or reactions .
3. Always Tetraethylammonium Chloride use appropriate personal protective equipment (PPE) including nitrile rubber gloves (minimum 0.11 mm thickness), tightly fitting safety goggles, and protective clothing to avoid skin, eye, and respiratory contact. Avoid dust formation and use with adequate ventilation .

1. Immediately isolate the spill area, use full personal protective equipment, and avoid generating dust. Contain Tetraethylammonium chloride CAS 56-34-8 using inert, non-combustible absorbent material and prevent entry into drains or waterways .
2. Carefully Tetraethylammonium Chloride sweep up or shovel the spilled solid without creating dust and place the collected material into a sealed, labeled chemical waste container for proper disposal according to local, state, and federal environmental regulations .
3. Personnel must wear suitable PPE, including self-contained breathing apparatus (SCBA) if necessary, during cleanup. For decontamination, scrub surfaces and equipment with alcohol .

1. Tetraethylammonium chloride CAS 56-34-8 is classified with GHS signal word "Warning". It causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335). It is harmful if swallowed (H302) with an acute oral LD50 in rats of 2,630 mg/kg .
2. Tetraethylammonium chloride is considered non-flammable (NFPA fire rating 0) and stable under recommended storage conditions, but thermal decomposition produces toxic and irritating fumes including carbon oxides, nitrogen oxides (NOx), and hydrogen chloride gas . It is toxic to aquatic life with long-lasting effects (H411, WGK Germany 3) .
3. Always Tetraethylammonium Chloride CAS 56-34-8 consult the specific Safety Data Sheet (SDS) for Tetraethylammonium chloride for complete hazard information, first-aid procedures, and handling instructions. Precautionary statements include P261 (avoid breathing dust), P273 (avoid release to environment), and P280 (wear protective gloves/eye protection) . It is not classified as a dangerous good for transport by some regulations.
