Diazald (N-Methyl-N-nitroso-p-toluenesulfonamide) is a chemical reagent commonly used in organic synthesis to generate diazomethane, a highly reactive compound. Diazomethane is widely utilized for methylation reactions, especially in converting carboxylic acids to methyl esters and preparing other methylated derivatives. Diazald is valued for its safer handling compared to direct use of diazomethane gas, as it allows for in situ generation under controlled conditions. It is frequently employed in laboratories due to its efficiency and versatility in various organic transformations. However, due to the hazards associated with diazomethane, including its toxicity and explosiveness, safety precautions are essential.
