Product Description:

1,3-Bis(chloromethyl)-1,1,3,3-tetramethyldisiloxane is an organosilicon compound featuring a disiloxane backbone with chloromethyl functional groups. It serves as a versatile bifunctional monomer and cross-linking agent in polymer chemistry. Its primary industrial application is in the synthesis and modification of silicone polymers. The reactive chloromethyl groups enable it to act as a key intermediate for introducing functional side chains or creating cross-linked networks, enhancing the thermal stability, mechanical properties, and adhesion of silicone resins, rubbers, and coatings. It is also utilized in the preparation of specialty materials like liquid silicone rubbers (LSR) and as a precursor for other organosilicon derivatives. As a reactive organosilane building block, it finds use in organic synthesis for constructing silicon-containing molecular architectures. Handling requires caution due to its moisture sensitivity, as it can hydrolyze to release hydrochloric acid.
