A sensitive liquid chromatography-tandem mass spectrometry (LC-MS) method was developed for the screening of five β-blockers (BBs), including atenolol, metoprolol, bisoprolol, propranolol, and betaxolol, in rabbit plasma. An inhouse prepared hydrazonoyl chloride compound (UOSA54) and dansyl chloride (DNS) were successfully
