Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 10351-75-4, name is 1H-Benzo[d]imidazole-5,6-dicarboxylic acid, A new synthetic method of this compound is introduced below., Formula: C9H6N2O4
2.2.2 H23-DPBB The above mentioned synthesis procedure was repeated except 3-aminobenzoic acid was used. Yield: 65.5%. Element analysis (%): Anal. Calc. C16H9N3O4: C 62.54, H 2.95, N 13.68. Found: C 62.60, H 2.92, N 13.69%. IR (KBr pellet, cm-1): 3310(m), 2520(m), 1780(vs), 1670(vs), 1600(m), 1550(m), 1480(vs), 1090(vs), 840(m), 776(m), 673(s), 543(s). Negative ESI-MS (m/z): 305.88 (H23-DPBB-H+). 1H NMR (DMSO-d6): delta: 7.669 (J = 1.6 Hz, t, 1H, Ph-H), 7.747 (J = 7.2 Hz, d, 1H, Ph-H), 7.995 (J = 8.0 Hz, d, 1H, Ph-H) 8.057 (s,1H, Ph-H) 8.104 (s, 1H, Ph-H) 8.201 (s, 1H, Ph-H), 8.596 (s, 1H, Im-H), 13.293 (s, 1H, COOH). Melting points: above 300 C.
The synthetic route of 10351-75-4 has been constantly updated, and we look forward to future research findings.
