In addition to its applications in traditional silicon materials, diphenyldichlorosilane also shows potential in fine chemicals and medical organosilicon materials.

As a silicon-based "protecting agent" or "blocking agent," diphenyldichlorosilane can be used in organic synthesis to protect active hydrogen groups such as hydroxyl, amine, thiol, and carboxyl groups, allowing it to participate in multi-step organic synthesis pathways. The protecting groups can be removed in the final stage through selective hydrolysis. Gelest lists it as a silicon-based blocking agent for protecting active hydrogens.

In addition, the compound is also considered an intermediate for synthesizing fine silicon-based building blocks in the pharmaceutical and fine chemical industries. Diphenyldichlorosilane is used in the synthesis of silicon-based compounds in the pharmaceutical industry.

In the electronic and medical silicon materials sector, demand for high-purity, low-impurity phenylsilane materials is increasing. IOTA 522 (high-purity diphenyldichlorosilane) is marketed for its suitability in high-end applications such as electronic packaging materials, medical silicon materials, seals, and coatings.

In the future, if there are breakthroughs in biocompatibility, biodegradable silicon materials, silicon-based drug carriers, etc., diphenyldichlorosilane will have the opportunity to enter higher value-added application scenarios as a "functionalized silicon skeleton unit."
