In this study, an indirect diastereomeric method and a direct method utilizing a chiral stationary phase (CSP) were investigated for the resolution of ibuprofen enantiomers. In the indirect method, ethylchloroformate (ECF) and 2-ethoxy-1-1-ethoxycarbonyl-1,2-dihydroquinoline (EEDQ) were utilized as first-step derivatizing reagents in acetonitrile or(More)
Immunogenicity assessment is important for biological products due to potential impacts of immunogenicity on safety and efficacy. We reviewed the prescribing information and the FDA’s clinical pharmacology review of 121 approved biological products for evaluating and reporting of immunogenicity data. Of the 121 products, 89% (n = 108) reported the incidence(More)
