AcroSeal Packagingby Acros Organics
Complete list of reagents with Acroseal available, please ask us.
PERFORMANCE The specially designed multi-layer septum ensures a better re-seal thus minimizing atmospheric exposure and protecting the quality of your air and moisture sensitive solvents and reagents.
CONVENIENCEA wide range of pre-prepared reagents in solution are available, reducing the risks and saving the time and effort of making your own.
SAFETYOur AcroSeal cap system ensures you can transfer the contents of the bottle safely into your reaction vessel minimizing your exposure to potentially hazardous che-micals.
Grignard ReactionThe Grignard reaction is an essential method in the formation of carbon-carbon bonds. In reactions involving GrignardReagents it is essential to exclude water and air, which rapidly destroy the reagent. Therefore, we provide these sensitivereagents in the industry-leading AcroSeal packaging, preventing the degradation of the reagents. An example of a reactionthat can be severely affected by the presence of water is the grignard reaction

• Halogen-Metal Exchange - The Halogen-metal exchange reaction was discovered in the late 1930s by Gilman and Wittig. The reaction is often used to prepare vinyl and aryllithium compounds from the more reactive alkyllithium
• Transmetallation - The organolithium compounds are very often used to prepare other metallorganic compounds through the transmetallation reaction.
• Anionic Polymerisation - A major industrial use of alkyllithium compounds, specifically n-Butyllithium, is the catalysis of the anionic polymerization of butadiene, isoprene and styrene.
Lithium Aluminium HydrideLithium aluminium hydride is an example of an extremely pyrophoric reducing agent, used in organic syn-thesis, especially for the reduction of esters, carboxylic acids and amides.
