7-Hydroxy-4-(trifluoromethyl)coumarin Chemical Properties, Uses, Production

Description

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

Chemical Properties

Off-white to light yellow or pink powder

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).

Synthesis

Ethyl 4,4,4-trifluoroacetoacetate

372-31-6

Resorcinol

108-46-3

7-HYDROXY-4-(TRIFLUOROMETHYL)COUMARIN

575-03-1

GENERAL METHOD: Iodine (25 mol%) was added to a mixture of resorcinol (5 mmol) and ethyl 4,4,4-trifluoroacetoacetate (6 mmol) in toluene (1 mL). The reaction mixture was heated and stirred at 90 °C for 18 h. The progress of the reaction was monitored by thin layer chromatography (TLC). After completion of the reaction, the mixture was cooled to room temperature, diluted with ethyl acetate (10 mL) and washed with distilled water (10 mL). The combined organic layers were dried with anhydrous sodium sulfate and the solvent was removed by evaporation under reduced pressure. The product was purified by fast column chromatography (silica gel, eluent: hexane/ethyl acetate = 95/5 to 80/20).
