Potassium 4-(acetoacetylamino)benzenesulfonate(CAS: 70321-85-6)

Potassium 4-(acetoacetylamino)benzenesulfonate is a white crystalline solid with a molecular weight of approximately 334.26 g/mol. It has a solubility of about 1.2 g/L in water. The compound is moderately reactive, particularly with strong acids and bases. It is stable under normal storage conditions but should be protected from moisture and heat.

Potassium 4-(acetoacetylamino)benzenesulfonate is typically synthesized by the reaction of 4-acetoacetylamino benzenesulfonyl chloride with potassium hydroxide in an aqueous medium. The reaction is catalyzed by a phase transfer catalyst, such as tetrabutylammonium bromide, to improve the yield and selectivity. The product has a yield of around 80-90%.

Potassium 4-(acetoacetylamino)benzenesulfonate finds applications in the pharmaceutical industry for the synthesis of certain drugs. It is also used in the polymer industry as a precursor for the preparation of polymeric materials. Additionally, it is employed in the production of sensors and as a reagent in analytical chemistry.

Precautions when handling Potassium 4-(acetoacetylamino)benzenesulfonate include the use of personal protective equipment (PPE), such as gloves, goggles, and a lab coat. The compound should be stored in a cool, dry place away from moisture and heat. Spills should be handled with caution using appropriate absorbent materials. An SDS (Safety Data Sheet) should be consulted for detailed safety information.
