Collection: Siloxanes [Organosilicon]

Siloxanes [Organosilicon] — contains linear and cyclic siloxane compounds with a Si-O-Si bonded framework substituted with methyl, vinyl, or phenyl groups, representing a category of functional organosilicon reagents. Variations in chain length and substituent type determine physical properties such as viscosity and compound polarity.

These siloxanes are used in polymer and materials chemistry research as precursors for polysiloxane synthesis, surface modification agents, and building blocks for silicone elastomers and functional coatings. Vinyl-substituted derivatives are commonly used in hydrosilylation reactions and crosslinked network formation, while the trimethyl-trivinyl cyclic siloxane is utilized as a monomer for synthesizing specialty silicone copolymers.

Consider the number of siloxane units in the chain or ring as well as the substituent type (methyl, phenyl, vinyl), which determine viscosity and reactivity, and ensure the packaging format suits the handling requirements of moisture-sensitive compounds. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
