CAS 455-36-7 — 3-Fluoroacetophenone

3-Fluoroacetophenone is an aromatic ketone with a fluorine substituent, widely used as a synthetic intermediate in pharmaceuticals, agrochemicals, and organic electronics. It serves as a key building block in the preparation of APIs, fluorinated polymers, and liquid crystal materials due to its reactive acetyl group and electron-withdrawing fluorine atom. This chemical is a pale yellow to colorless liquid with a CAS number of 455-36-7, boiling point of 215–217°C, and density of ~1.18 g/cm³. It is soluble in organic solvents like ethanol, acetone, and dichloromethane but poorly soluble in water. Non-hazardous classification applies (no signal word), though standard lab precautions for ketones should be followed. Molekula supplies 3-Fluoroacetophenone from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
