| | 4-Bromomethyl-7-methoxycoumarin Usage And Synthesis |
| Chemical Properties | Light Green-Yellow Crystals | | Uses | 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
- as derivatization reagent in fluorescence detection of sodium monofluoroacetate (MFA-Na) in biological samples by HPLC
- 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)
- in TLC and HPLC separation and fluorometric analysis of a wide range of naturally occurring acids, including bile and thromboxane B2
| | Uses | 4-Bromomethyl-7-methoxycoumarin can be used as fluorescent label for fatty acids. For derivatization, TLC and HPLC separation, and fluorometric analysis of a wide range of naturally occurring acids, including bile and thromboxane B2. | | Purification Methods | The coumarin crystallises from boiling AcOH; the crystals are washed with AcOH, EtOH and dried in a vacuum; 1HNMR (TFA) 3.97s, 4.57s, 6.62s, 6.92-7.19m and 7.80d.
