4-(4-Fluorobenzoyl)butyric acid is a key pharmaceutical intermediate primarily used in the synthesis of cholesterol absorption inhibitors like ezetimibe. This compound exhibits a melting point of 142-144°C and boiling point of 394.6±22.0°C at 760 mmHg, with a density of 1.2±0.1 g/cm³. The material should be stored in sealed containers at room temperature, protected from moisture. Safety precautions include wearing protective gloves and eye/face protection due to potential skin/eye irritation (GHS Category 2). Its molecular structure containing both fluorobenzoyl and carboxylic acid functionalities makes it valuable for constructing bioactive molecules with improved metabolic stability.
