Applications & Uses

Description

7-Hydroxy-4-(trifluoromethyl)coumarin can be used as a reference standard for fluorescent pH indicator.

Uses

Suitable as pH-indicator. Trifluoromethylumbelliferone is a slightly longer wavelength analog of 4-methylcoumarin (4-MU) with a pKa that more closely matches physiological pH values.

Uses

7-Hydroxy-4-(trifluoromethyl)coumarin is an halogenated metabolite of Coumarin (C755380), an naturally occurring organic compound that exists in many plants. Coumarin is the precursor molecule in the synthesis of various synthetic anti-coagulant such as warfarin (W498500)/.

General Description

7-Hydroxy-4-(trifluoromethyl)coumarin is a class of 7-hydroxycoumarin that is majorly used as laser dyes. It has a characterized emission spectra and may be used in excited state proton transfer (ESPT).
