| Application: | Ammonium phosphate monobasic can be used to study optimization reagents, protein structural analysis, proteomics, x-ray crystallography and biological buffers. Ammonium phosphate monobasic has been used to develop a simple high-performance liquid chromatographic method for determining N1-alkylnicotinamides, including C1C5 alkyl derivatives, in urine. Ammonium phosphate monobasic has also been used to develop a high-performance liquid chromatographic assay coupled with UV detection (254 nm) for the determination of midazolam and two of its hydroxylated metabolites in human plasma. |
