N,N,N',N'-Tetraethylphosphorodiamidous chloride(CAS: 685-83-6)

N,N,N',N'-Tetraethylphosphorodiamidous chloride is a colorless or white crystalline solid with a molecular weight of approximately 263.45 g/mol. It is slightly soluble in water but soluble in organic solvents like ethanol and acetone. Chemically, it is highly reactive, particularly in the presence of moisture or heat, and can undergo hydrolysis or other degradation reactions.

N,N,N',N'-Tetraethylphosphorodiamidous chloride is typically synthesized by reacting phosphorus oxychloride with ethylamine in the presence of a catalyst such as pyridine. The reaction involves the displacement of chlorine atoms from phosphorus oxychloride by ethyl groups, yielding the desired product with high selectivity and yield.

N,N,N',N'-Tetraethylphosphorodiamidous chloride is used in the pharmaceutical industry for the synthesis of certain drugs, in the polymer industry for stabilizing and modifying polymers, and in semiconductor manufacturing for etching and cleaning processes. It also has applications in sensor technology and as a reagent in organic synthesis.

When handling N,N,N',N'-Tetraethylphosphorodiamidous chloride, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a laboratory coat. The compound should be used in a well-ventilated area or a fume hood to minimize exposure. Spills should be handled carefully, and the Material Safety Data Sheet (MSDS) should be referenced for detailed spill cleanup procedures. Ensure good laboratory hygiene practices and dispose of waste according to local regulations.
