p-Cresol-d7 is a validated reference standard that has been prepared to meet the requirements of ISO 11172. p-Cresol-d7 is an important metabolite of catecholamines and is used for the analysis of human serum, as well as in diagnostic assays for the detection of chronic kidney disease. This compound is also used to study matrix effects on chromatographic techniques, such as LC-MS/MS methods. The molecular weight of p-cresol-d7 is 146. br> br>This product was prepared by acetylation of 4-(2,4-dinitrophenyl)-1,2,5,6-tetrahydropyrimidine with acetic anhydride and pyridine in methanol at room temperature. The reaction was monitored by thin layer chromatography (TLC). The crude product was purified using a silica column with hexane as eluent
