- Mitsunobu Reaction Using Tsunoda Reagent
- TCI SpectraViewer
Photoredox Catalysts / Photosensitizers
Visible light photoredox catalysts are metal complex catalysts and organocatalysts that work for both one-electron oxidation and reduction under visible light irradiation. They have the potential to be used as a solar energy source and can form radical species under mild conditions. Recent progress in photoredox catalysis has been remarkable, with many new applications being developed. We offer the latest catalysts; [Ir(dFCF3ppy)2-(5,5'-dCF3bpy)]PF6 [B6451], peri-Xanthenoxanthene [X0083] and Acr-450 [D5983].
DualSeal ― Airtight-Double-Cap Bottled Reagents
DualSeal is a TCI developed double cap system for moisture/oxygen sensitive products, allowing you to keep reagents in good condition until the last drop. DualSeal consists of two parts; the blue outer cap and the white septum cap, both of which can be screwed on and off. No additional sealing is required after piercing the septum cap with a needle. Just screw the outer cap back in place. You can see the video of instructions for use and precautions.
TCI Practical Example: 2,2,2-Trifluoroethyl Etherification Using 2,2,2-Trifluoroethyl p-Toluenesulfonate
We are proud to present the synthesis of 4-(2,2,2-trifluoroethoxy)acetophenone from 4'-hydroxyacetophenone and 2,2,2-trifluoroethyl p-toluenesulfonate [T1516].
TCI Practical Example: Mitsunobu Reaction Using Tsunoda Reagent
TCI introduces the etherification of 3,4-dihydro-7-hydroxy-2(1H)-quinolinone with 4-(2-hydroxyethyl)morpholine by the Mitsunobu reaction using Tsunoda reagent [C1500].
[New] TCI SpectraViewer
We have launched a convenient tool for checking the excitation and fluorescence spectra of fluorescent dyes, including our products. By selecting the name of the fluorescent dye, the spectrum will be displayed. You can also search for fluorescent dyes suitable for your filters or lasers. It is also possible to indicate the wavelength of filters or lasers in the figure. Please see also a usage page.
