Description

TCI D3842 4,7-Dibromo-2,1,3-benzothiadiazole, CAS number 15155-41-6, is a heterocyclic compound built around a benzothiadiazole ring carrying two bromine atoms at the 4 and 7 positions. It is one of the most important monomers in organic electronic chemistry and conjugated polymer synthesis. Its role in the laboratory is to serve as an electron-accepting unit and, at the same time, as a two-directional connection point: the two bromine atoms provide reactive positions for cross-coupling reactions, allowing the benzothiadiazole unit to be assembled together with donor units into long conjugated chains or neatly structured small molecules.

The property that makes this compound the preferred choice is its strong electron-withdrawing ability, which comes from the nitrogen and sulfur atoms in the ring and produces a clear acceptor character in donor–acceptor systems. This character is the basis for tuning the energy gap, the light absorption, and the charge-carrier properties of the synthesized material. The symmetrical placement of the bromine atoms makes directed polymerization straightforward, and it also allows two different groups to be attached in sequential steps. The framework is planar and thermally stable as well, so it suits materials that are processed by heating or by solution coating.

In Indonesian laboratories, this building block is typically used in university and institutional research groups working on organic electronic materials and conjugated polymer synthesis. It is handled in synthetic chemistry and materials chemistry work where donor–acceptor architectures are prepared step by step, then characterized and processed into thin films. Because it is supplied as a defined single compound with a stated CAS number, it fits routine research procedures in which the acceptor unit must be reproducible from one synthesis batch to the next.

Laboratory Applications

Conjugated polymer synthesis — the two bromine positions act as reliable coupling handles, so the benzothiadiazole unit can be polymerized with donor comonomers into long conjugated chains.
Donor–acceptor small molecule construction — the symmetrical dibromo substitution permits two different donor groups to be attached in sequential steps, giving neatly structured target molecules.
Organic electronic material development — the strong electron-withdrawing ring supplies the clear acceptor character needed when energy gap and light absorption must be deliberately tuned.
Cross-coupling reaction work — the reactive bromine sites at the 4 and 7 positions make this compound a standard substrate for building extended conjugation through cross-coupling chemistry.
Solution-processed and thermally processed film studies — the planar, thermally stable framework suits materials intended for processing by heating or by solution coating methods.

Handling and Storage

Store the compound in its original tightly closed container in a cool, dry, well-ventilated area, protected from light and moisture and kept away from incompatible reagents. Amber glass or the supplier's original packaging is suitable; transfer only what is needed and reseal promptly to avoid moisture uptake. Handle the solid in a fume hood using gloves, safety glasses, and a laboratory coat, and avoid generating or inhaling dust. Weigh and transfer with clean, dry spatulas to prevent contamination between batches. Label all secondary containers clearly, keep the manufacturer safety data sheet accessible before first use, and dispose of residues and contaminated consumables through the laboratory's chemical waste route rather than the general drain or bin.
