4-Iodobenzoic Acid CAS 619-58-9

1. 4-Iodobenzoic acid serves as a key pharmaceutical intermediate for synthesizing anti-inflammatory and analgesic drugs, as well as anti-infective and contraceptive agents .
2. 4-Iodobenzoic acid CAS 619-58-9 is widely used in organic chemistry as a building block for iodinated compounds, cross-coupling reactions, and the cleavage of alkenes via in situ [hydroxy(4-carboxyphenyl)iodonium]ion formation .
3. 4-Iodobenzoic acid has applications in material science for polymers with enhanced thermal stability, in biochemical research for enzyme inhibition studies, and as an X-ray contrast medium for diagnostic radiology .

1. Store 4-Iodobenzoic acid in a tightly sealed container at room temperature (RT) in a cool, dry, well-ventilated place, protected from light as 4-Iodobenzoic acid is light-sensitive .
2. Keep 4-Iodobenzoic acid CAS 619-58-9 strictly away from strong oxidizing agents and strong bases due to incompatibility .
3. Handle 4-Iodobenzoic acid using appropriate personal protective equipment including nitrile gloves and safety goggles, and avoid breathing dust by working in a well-ventilated area or fume hood .

1. Isolate the spill 4-Iodobenzoic acid CAS 619-58-9 area, wear suitable protective equipment including dust mask, and sweep up solid 4-Iodobenzoic acid into sealed, labeled containers without creating dust .
2. Prevent spilled 4-Iodobenzoic acid from entering drains or waterways, as 4-Iodobenzoic acid is toxic to aquatic life with long-lasting effects .
3. Personnel cleaning 4-Iodobenzoic acid spills must dispose of waste according to environmental regulations and ensure contaminated clothing is washed before reuse .

1. 4-Iodobenzoic acid causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) with GHS signal word "Warning" .
2. 4-Iodobenzoic acid CAS 619-58-9 is an irritant (Xi) with risk phrases 36/37/38 and has an intravenous LD50 of 2,500 mg/kg in mice .
3. Combustion of 4-Iodobenzoic acid produces toxic fumes including carbon oxides and hydrogen iodide, and 4-Iodobenzoic acid has a flash point >110°C with melting point of 270-273°C .
