CAS :<p>3-(2-Hydroxyethyl)-2-methyl-4H,6H,7H,8H,9H-pyrido[1,2-a]pyrimidin-4-one is an impurity in the drug paliperidone. It is a pyridinic acid derivative and has been used as a ligand in X-ray crystallography to identify protein structures. 3-(2-Hydroxyethyl)-2-methyl-4H,6H,7H,8H,9H-pyrido[1,2-a]pyrimidin-4 one is also known to have high detection sensitivity and can be used to analyze ammonium formate. This impurity has been detected in the urine of patients taking paliperidone extended release tablets. To remove this impurity from the drug paliperidone, it must be purified by liquid chromatography or liquid chromatography with high performance liquid chromatography (</p>Formule :C11H16N2O2Degré de pureté :Min. 95%Masse moléculaire :208.26 g/mol
