Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. SDS of cas: 652-12-0. Introducing a new discovery about 652-12-0, Name is Tetrafluorophthalic anhydride
The invention discloses a method for detecting cysteine fluorescence probe and its preparation method and method of use. This invention utilizes the phthalimide framed classical intramolecular charge transfer (ICT) system, and a benzene ring is introduced into the remaining positions in the four atomic fluorine, make it more biological stability and optical stability. The probe itself is a fluorine atom inhibit the ICT effect without fluorescence emission, but under the conditions when there is a cysteine, fluorine atom is cysteine substituted, and then make its inhibiting effect disappears, the probe molecule emits strong fluorescence. The invention provides N – butyl four-phthalic acid imide dye “on – off” type cysteine probe to cysteine solution has a good response, can be realized to the sample of the trace in the cysteine of the sensitive quantitative detection, has simple operation, low cost, and sensitive response, easy popularization and application and the like.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 652-12-0, you can also check out more blogs about652-12-0
