| Application |
Heptamethyltrisiloxane is a versatile colourless liquid that serves as a catalyst for reduction reactions in organic syntheses. This essential compound is a fundamental material for producing synthetic polyalkyleneoxide modified heptamethyltrisiloxane, a specific structure surfactant widely used in pesticide additives and coating additives. Furthermore, heptamethyltrisiloxane is a key raw material and intermediate for organic synthesis, pharmaceuticals, and dyestuffs. Its applications extend to aromatic C-H silylation of arenes, as well as the synthesis of various compounds such as 3-Octyl-1,1,1,3,5,5,5-heptamethyltrisiloxane for agricultural adjuvants and sensory performance enhancers in cosmetics. Moreover, this compound can be utilized in the production of Isoindigo-based conjugated polymers and Monosiloxy esters with diverse acids. |
