3-Fluorobenzoic Acid CAS 455-38-9

1. 3-Fluorobenzoic acid CAS 455-38-9 serves as a key intermediate in pharmaceutical development, particularly for synthesizing anti-inflammatory and analgesic drugs . 3-Fluorobenzoic acid is also used in the preparation of compounds for regulating phenolic acid synthesis in *Bacillus subtilis* and in bacterial decarboxylation studies .
2. The compound is utilized in agrochemical formulations for herbicides and pesticides, and acts as a building block in polymer chemistry to create specialty materials with improved thermal and chemical resistance .
3. Applications of 3-Fluorobenzoic acid include its use as an analytical standard in chromatographic techniques and in the development of advanced materials such as coatings and adhesives requiring enhanced performance characteristics .

1. Store 3-Fluorobenzoic acid CAS 455-38-9 in a tightly sealed container in a cool, dry, and well-ventilated place, away from strong oxidizing agents . Recommended storage temperatures vary from refrigeration (0-8 °C) to room temperature in a cool, dark place below 15°C .
2. Keep 3-Fluorobenzoic acid away from strong oxidizing agents due to incompatibility, and protect from conditions that may generate dust or aerosols .
3. Always 3-Fluorobenzoic acid use appropriate personal protective equipment (PPE) including chemical-resistant gloves, protective clothing, and eye/face protection; avoid breathing dust and ensure adequate ventilation when handling 3-Fluorobenzoic acid .

1. Immediately isolate the spill area, avoid dust formation, and contain 3-Fluorobenzoic acid CAS 455-38-9 using inert, non-combustible absorbent material; prevent material from entering drains or waterways .
2. Carefully sweep up the spilled 3-Fluorobenzoic acid solid using clean, non-sparking tools and place the collected material into a sealed, labeled chemical waste container for proper disposal according to local, state, and federal environmental regulations.
3. Personnel 3-Fluorobenzoic acid must wear suitable PPE during cleanup; under fire conditions, wear self-contained breathing apparatus (SCBA) as thermal decomposition produces toxic and irritating fumes including carbon monoxide, carbon dioxide, and hydrogen fluoride.

1. 3-Fluorobenzoic acid CAS 455-38-9 is classified as an irritant (GHS signal word "Warning"), causing skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) .
2. 3-Fluorobenzoic acid has a melting point of 122-124°C and is very soluble in water . It is stable under normal conditions but incompatible with strong oxidizing agents. The compound is not classified as hazardous material for transport.
3. Always consult 3-Fluorobenzoic acid  the specific Safety Data Sheet (SDS) for 3-Fluorobenzoic acid for complete hazard information, first-aid procedures, and handling instructions; precautionary statements include P261 (avoid breathing dust), P264 (wash skin thoroughly after handling), and P280 (wear protective gloves/eye protection) .
