General description

4-Formylaminoantipyrines are grouped under the class of biodegradable organic micropollutants (OMPs).

Application

4-Formylaminoantipyrine may be used as an analytical reference standard for the determination of the analyte in:
  • Aqueous samples by ultra-high performance liquid chromatography-high resolution mass spectrometry (UHPLC-HRMS).
  • Groundwater, surface water and wastewater samples by online mixed-bed multilayer solid-phase extraction (SPE) and HPLC combined with tandem mass spectrometry (MS/MS).

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

A rapid solid-phase extraction (SPE) procedure was developed for the quantitative isolation of three important antipyrine (dipyrone) metabolites from human plasma: 4-formylaminoantipyrine (FAA), 4-aminoantipyrine (AA) and 4-methylaminoantipyrine (MAA). Separation and quantitation were performed using micellar liquid chromatography (MLC) with a
