1,1'-Sulfonylbis(1H-imidazole)(CAS: 7189-69-7)

1,1'-Sulfonylbis(1H-imidazole) is a crystalline solid with a molecular weight of approximately 222.2 g/mol. It has a pKₐ of about 7.5 and is slightly soluble in water. The compound is reactive towards nucleophiles and can undergo substitution reactions. It is stable under normal storage conditions but should be kept away from strong acids and bases.

1,1'-Sulfonylbis(1H-imidazole) is typically synthesized through the reaction of two equivalents of imidazole with sulfonyl chloride, catalyzed by a suitable base such as triethylamine. The reaction proceeds via an imidazole dimerization followed by sulfonation. The yield is usually around 85%, and the product is isolated by recrystallization from ethanol.

1,1'-Sulfonylbis(1H-imidazole) finds applications in the pharmaceutical industry as a precursor in the synthesis of bioactive compounds. It is also used in the polymer industry for the modification of polymers and in sensor technology for its ability to act as a sensing element. Additionally, it is utilized in the semiconductor industry for its conductivity properties.

Proper personal protective equipment (PPE) must be worn when handling 1,1'-Sulfonylbis(1H-imidazole). This includes gloves, goggles, and a lab coat. The material should be handled in a well-ventilated area or a fume hood to prevent inhalation. Spills should be cleaned up using appropriate absorbent materials and disposed of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
