Product of Arkema Inc. Dimethyl disulfide (DMDS) may be used to derivatize alkenes for the determination of position of double bond by MS. It may also be used to determine the location of the double-bond position of monounsaturated fatty acids in Campylobacter cryaerophila by combined GC-MS analysis.
Methyl Hydrogen Siloxanes. â¢ Possible applications include precursors to polyorganosiloxanes, cross-linking agents and chain extenders. â¢ Both silicone hydride homopolymers and dimethyl-copolymers are used to prepare polyorganosiloxanes; short chain. SiH-terminated fluids find applications as chain extenders and ABAin co-polymer manufacture. â¢ Hydrosilylation, the addition of a silicone hydride moiety across an unsaturated linkage, catalyzed by transition metal. complexes of rhodium or platinum, is commonly applied to the preparation of organofunctional siloxanes. Condensation cure chemistry is also widely used for preparation of crosslinked polymer matrices.
