4,7-Dibromo-[1,2,5]thiadiazolo[3,4-c]pyridine(Cat No.:L011938)is a halogenated heterocyclic compound containing a fused thiadiazole-pyridine ring system with bromine atoms at the 4- and 7-positions. This electron-deficient, aromatic scaffold is valuable in the synthesis of π-conjugated materials, particularly for applications in organic electronics, photovoltaics, and optoelectronic devices. The dibromo substitution allows for palladium-catalyzed cross-coupling reactions (e.g., Suzuki or Stille) to introduce various donor or acceptor groups, facilitating the design of materials with tailored electronic properties. Its rigidity and electron-withdrawing nature make it a key building block in low-bandgap polymers and semiconductors.
