Synthesis and spectroscopic studies of trans-bis-(3,5-dimethyl-4-nitrosopyrazole) dimer

Bis-(3,5-dimethyl-4-nitrosopyrazole) dimer was prepared by reaction of acetyl acetone with nitrous acid and condensation with hydrazine. Spectroscopic techniques, such as IR, UV, 1H NMR, and 13C NMR, and CHN analysis were used to identify the product.
