| | Triton X-100 Usage And Synthesis |
| Description | Triton X-100 is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average it has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group. The hydrocarbon group is a 4-(1,1,3,3-tetramethylbutyl)-phenyl group. Triton X-100 is closely related to IGEPAL CA-630 or former Nonidet P-40, which might differ from it mainly in having slightly shorter ethylene oxide chains. Thus Triton X-100 is slightly more hydrophilic than Igepal CA-630; these two detergents may not be considered to be functionally interchangeable for most applications.
Triton X-100 is a common non-ionic surfactant and emulsifier which is often used in biochemical applications to solubilize proteins. It is considered a comparatively mild detergent, non-denaturing, and is reported in numerous references as a routinely added reagent. It is utilized for lysing cells to extract protein and cellular organelles. It can also permeabilize the living cell membrane for transfection. | | Chemical Properties | Triton X-100 is a very stable material, assumed to be stable for years if stored sealed. It is a clear to slightly hazy, colorless to light yellow liquid (color by APHA = 100).
1. Specific gravity: 1.065 at 25°C (Approx. 1.07 g/mL).
2. Approximate molecular weight = 625, giving effective molarity = 1.7 M for the neat liquid.
3. UV absorption: lambda max = 275 nm and 283 nm in methanol.
4. Viscosity (Brookfield): 240 cps at 25°C.
5. pH (5% aqueous solution): 6.0 to 8.0.
6. Critical micelle concentration (CMC): 0.22 to 0.24 mM. | | Uses | Nonionic detergent, emulsifier, dispersing agent. Octoxynol-9 as spermaticide. | | Uses | Triton-X 100 is a non-ionic surfactant. Used in the enhancement of film porosity in conducting polymers. | | Uses | Detergent, equivalent to Nonidet P-40.Triton X-100 is used as a non-ionic detergent, emulsifier and dispersing agent. It is useful for isolation of membrane proteins. It is also used in electrophoresis. It is an active ingredient in influenza vaccine (Fluzone). It finds applications in the dispersion of carbon materials for soft composite materials and restricting colony expansion in Aspergillus nidulans in microbiology. Further, it is an active ingredient in homemade vinyl record cleaning fluids together with distilled water and isopropyl alcohol. | | Definition | ChEBI: A poly(ethylene glycol) terminated with a 4-(2,4,4-trimethylpentan-3-yl) phenyl group at one end. | | Brand name | Triton X-100 (Union Carbide). | | General Description | Triton X-305 is a non-ionic surfactant. This octylphenol ethoxylate has higher number of ethylene oxide units, increased cmc (Critical micelle concentration) and hydrophile/lipophile balance when compared to Triton X-100. Triton X-305 is compatible with anionic, cationic, and other nonionic surfactants and chemically stable in most acidic and alkaline solutions.
Triton X-100 is a nonionic detergent, 100% active ingredient, which is often used in biochemical applications to solubilize proteins. Triton X-100 has no antimicrobial properties. It is considered a comparatively mild detergent, non-denaturing, and is reported in numerous references as a routinely added reagent. It does absorb in the ultraviolet region of the spectrum, however, so can interfere with protein quantitation. A number of polymeric resins have been used to remove X-100 from solution, including Amberlite hydrophobic XAD resins and Rezorian A161 cartridges. The "X" series of Triton detergents are produced from octylphenol polymerized with ethylene oxide. The number ("-100") relates only indirectly to the number of ethylene oxide units in the structure. X100 has an "average of 9.5" ethylene oxide units per molecule, with an average molecular weight of 625. In addition, lower and higher mole adducts will be present in lesser amounts, varying slightly within supplier's standard manufacturing conditions. No antioxidants are added by Sigma or the manufacturer, but commercial preparations of Triton X-100 have been found to contain peroxides up to 0.22% hydrogen peroxide (H2O2) equivalents. These impurities may interfere with biological reactions. Sigma offers X-100-PC and X-100R-PC as biological grade alternatives. | | Safety Profile | Moderately toxic by
