Benzoguanamine is a multifunctional compound with applications in the following areas:
(1) Dye-sensitized solar cells (DSSCs): A benzoguanamine-doped PVDF/KI/I₂ electrolyte was prepared via solution casting. The electrolyte membrane exhibited an ionic conductivity of 1.21 × 10⁻⁵ S cm⁻¹, demonstrating higher amorphous properties. This material can be further used to prepare DSSCs.
(2) Fluorescent sensors: Benzoguanamine dimers were used as novel fluorescent probes to detect mercury ions (Hg²⁺) in fish samples.
(3) Porous carbon materials: High-specific-surface-area porous carbon was prepared by carbonizing benzoguanamine polyacetal and activating it with KOH. This carbon exhibited excellent CO₂ trapping capacity (2.84 mmol/g at 273 K) and N₂ selectivity (39.6 at 273 K).
(4) Nanocatalysts: Nickel complexes based on benzoguanidine were used as highly efficient heterogeneous nanocatalysts. Various 2-phenyl-1H-benzo[d]imidazoles were synthesized by reacting o-phenylenediamine (PhenDA) with various aldehydes in chloroform under reflux conditions.

Benzoguanamine closely resembles melamine in that reaction with formaldehyde gives methylol derivatives and then resinous condensates. Butylated benzoguanamine-formaldehyde resins have found some use in surface coatings. In a typical preparation, benzoguanamine (1 mole) is heated with formalin (3 mole formaldehyde) at pH 8.3 and 70-80°C until the guanamine has dissolved. n-Butanol (9 mole) and a small amount of hydrochloric acid are added and the azeotrope distilled off until removal of water is complete. Like their melamine counterparts, butylated benzoguanamine-formaldehyde resins are most commonly used in admixture with alkyd resins. The resulting coatings are very similar to those based on melamine but they show improved resistance to alkalis.
