| Vinylsulfone-PEG5K-Vinylsulfone | average Mn 5,000. Group: Poly(ethylene glycol) and poly(ethylene oxide). |  |
| Vinylsulfone-PEG5K-Vinylsulfone | Polyethylene glycol (PEG) compounds contain a polyether unit, commonly expressed as R1-(O-CH2-CH2)n-O-R2. They are generally biocompatible, non-toxic and stable in both organic and aqueous solutions, and so are extensively used in biological applications, as well as nanotechnology and materials research. Proteins with PEG chain modifications and compounds encapsulated in PEG liposomes exhibit a longer half-life in vivo than their non-PEGylated counterparts, a phenomenon known as PEG shielding. Functionalised PEG lipids and phospholipids can be used for protein-PEG conjugation. Uses: Activated peg derivatives can be used to modify peptides, proteins, or in other bioconjugation applications. pegylated materials have found broad use in drug delivery systems, virology, and immunology, as the incorporation of peg improves pharmacological properties such as increased water solubility, enhanced resistance to degradation (protein hydrolysis), increased circulation half-life, and reduced antigenicity. in addition to pegylation, activated peg derivatives can also be used to form networks for tissue engineering or drug delivery applications, depending on the architecture and reactivity. Group: Poly(ethylene glycol) and poly(ethylene oxide). Alternative Names: Vinylsulfone-PEG-Vinylsulfone, VS-PEG-VS. Molecular formula: average Mn 5000. | |

| Vinyltrimethoxysilane | It is used to modify polyethylene and other polymers by grafting its vinyl groups onto the polymer backbone using free radical initiators such as peroxides. This provides polymers with pendant trimethoxysilyl groups that can be used as moisture-activated crosslinking sites by hydrolysis of alkoxy groups and then condensation of the resulting silanol. When the silane-grafted polyethylene reacts to form a cross-linked or vulcanized polyethylene, cross-linked bonds are formed with water. This technology is widely used worldwide in commercial applications for wire and cable insulation, pipes and other similar purposes. The basic reaction sequence is as follows: using a peroxide initiator, reacting (grafting) polyethylene with vinyltrimethoxysilane in an extruder. The grafted polyethylene is then formed into final products, such as cable jackets, wire insulation or pipes. The forming step is usually completed by a second extrusion, during which the catalyst for the moisture curing step is added. Finally, due to the hydrolysis and condensation of the silane, the formed article is exposed to moisture or hot water, and the condensation forms a crosslink through the formation of Si-O-Si bonds. Uses: It can be used for polymer modification and polymer crosslinking. Group: Polymers.

| Violaxanthin | analytical standard. Group: Colorant standards. | |
| violaxanthin de-epoxidase | Along with EC 1.14.13.90, zeaxanthin epoxidase, this enzyme forms part of the xanthophyll (or violaxanthin) cycle for controlling the concentration of zeaxanthin in chloroplasts. It is activated by a low pH of the thylakoid lumen (produced by high light intensity). Zeaxanthin induces the dissipation of excitation energy in the chlorophyll of the light-harvesting protein complex of photosystem II. In higher plants the enzyme reacts with all-trans-diepoxides, such as violaxanthin, and all-trans-monoepoxides, but in the alga Mantoniella squamata, only the diepoxides are good substrates. Group: Enzymes. Synonyms: VDE. Enzyme Commission Number: EC 1.23.5.1. CAS No. 57534-73-3. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C.
