TCI C1121 3-Chloro-4-fluorophenol (CAS 2613-23-2) is a halogenated phenol that serves as a compact fluorinated building block. The phenolic hydroxyl supports etherification, esterification, and coupling chemistry, while the aromatic chlorine can act as a handle for palladium catalysed cross coupling. Fluorine substitution is frequently used in medicinal and agrochemical research to tune lipophilicity and metabolic behaviour. AMI Scientific supplies a 10 g pack; store it cool, dry, protected from light, and handle it in a fume hood.
