1,1,3,3-Tetrabutylurea(CAS: 4559-86-8)

1,1,3,3-Tetrabutylurea (CAS: 4559-86-8) is a white crystalline solid with a molecular weight of 238.36 g/mol. It has poor solubility in water but is soluble in organic solvents. Chemically, it is moderately reactive, particularly under basic conditions, making it useful in a variety of synthesis applications.

1,1,3,3-Tetrabutylurea is typically synthesized by the reaction of 1,3-dibutylurea with butanol in the presence of a strong acid catalyst, such as hydrochloric acid. The reaction is carried out under mild conditions, and the yield can be up to 85%. The product is then purified by recrystallization.

1,1,3,3-Tetrabutylurea is used in various industries, including pharmaceuticals, where it serves as a raw material for drug synthesis, and in polymer production for its ability to enhance properties such as viscosity and solubility. It is also used in the production of sensors and semiconductors due to its reactivity and stability.

When handling 1,1,3,3-Tetrabutylurea (CAS: 4559-86-8), it is important to wear appropriate personal protective equipment (PPE), including gloves and safety goggles. The substance should be handled in a well-ventilated area or a fume hood to prevent inhalation. In case of a spill, it should be cleaned up using appropriate absorbents, and the area should be thoroughly cleaned. Always consult the Material Safety Data Sheet (MSDS) for detailed safety information.
