Application

4-Bromomethyl-7-methoxycoumarin has been used:
  • as derivatization reagent in determination of 5-fluorouracil (5-FU) in human plasma by HPLC-tandem mass spectrometry[1]
  • as derivatization reagent in fluorescence detection of sodium monofluoroacetate (MFA-Na) in biological samples by HPLC[2]
  • in the synthesis of new caged derivatives of hydrolysis-resistant 8-bromoadenosine cyclic 3′,5′-monophosphate (8-Br-cAMP) and 8-bromoguanosine cyclic 3′,5′-monophosphate (8-Br-cGMP)[3]
  • in TLC and HPLC separation and fluorometric analysis of a wide range of naturally occurring acids, including bile[4] and thromboxane B2[5]
Fluorescent label for fatty acids.

New caged derivatives of hydrolysis-resistant 8-bromoadenosine cyclic 3',5'-monophosphate (8-Br-cAMP) and 8-bromoguanosine cyclic 3',5'-monophosphate (8-Br-cGMP) are described. The compounds are the axial and equatorial isomers of the (7-methoxycoumarin-4-yl)methyl (MCM) esters of cyclic nucleotides. Synthesis is accomplished by treatment of 4-bromomethyl-7-methoxycoumarin with
