The aim of using exclusive hadronic decays of a B–meson into two light mesons is the determination of CKM parameters and the detection of New Physics entering in these decays. Within the framework of QCD factorization the dominant corrections from QCD are calculated in a systematic way. After a short introduction into the framework I will discuss the hadronic uncertainties in comparison to the case of pseudoscalar final states and show the implications on CKM observables. The talk will focus on some chosen applications to specific decay modes and the precision of CKM observables that can be extracted from them. An application is the discussion of a New Physics scenario which will be testable with high precision in future experiments.
