This study employs Raman spectroscopy for the first time to characterize (Z)- N-(2-amino-1,2-dicyanovinyl) formimidate. Raman, in addition to IR and NMR (acquired and literature), helps confirm the molecular structure of the compound. Additionally, the melting point (mp 132˚C - 134˚C) data helps confirm the compound’s purity. Raman spectra, measured with a 785 nm laser, reveal key vibrational modes, including two peaks at 2242 and 2206 cm−1 (CN stretches), two peaks at 1634 and 1591 cm−1 (C=N and C=C stretches), two peaks at 1369 and 1224 cm−1 attributed to (C-O and N-H bands). The acquired FT-IR spectra showed characteristic peaks at 3416, 3304, 2243, 2208, 1635, 1606 cm−1 as reported by IR data of Alves et al (1990) [1] and US Patent #US 8,518,901 B2 (2013) [2] at 3309 cm−1 (NH/NH2 stretches), 2247 cm−1 (CN stretches), 2207 cm−1 (CN stretches)~1636 cm−1 (C=N stretches), 1608, 1256 (C-0 str.), 810 cm−1 supporting the presence of cyano, formimidate, and amino groups. These findings validated the compound’s identity and highlighted the complementary nature of Raman and IR techniques for formimidate analysis.
