5-Bromo-2-Chlorobenzoic Acid CAS 21739-92-4

1. 5-Bromo-2-chlorobenzoic acid CAS 21739-92-4 is primarily used as a versatile intermediate in organic synthesis, particularly for pharmaceuticals and agrochemicals.
2. 5-Bromo-2-Chlorobenzoic acid serves as a key building block for the preparation of active pharmaceutical ingredients (APIs) and other halogenated aromatic compounds.
3. This compound is also utilized in research for the development of new materials, ligands, and biologically active molecules.

1. Store 5-bromo-2-chlorobenzoic acid CAS 21739-92-4 in a cool, dry, well-ventilated place, away from heat, sparks, and open flames.
2. Keep the container tightly closed and separated from strong oxidizing agents, strong bases, and reducing agents.
3. Handle 5-Bromo-2-Chlorobenzoic acid with appropriate personal protective equipment (PPE), including chemical-resistant gloves, safety goggles, and a lab coat. Use local exhaust ventilation or a fume hood to avoid inhalation of dust.

1. Isolate the spill area, ensure ventilation, and wear suitable protective equipment (gloves, goggles, protective clothing, and a dust mask/respirator).
2. Carefully 5-Bromo-2-Chlorobenzoic acid collect the spilled solid with a clean, non-sparking tool. Avoid creating dust. Place the contaminated material in a sealed, labeled container for hazardous waste disposal.
3. Prevent the material from entering drains, sewers, or the environment. Clean the contaminated surface thoroughly with water and detergent, collecting the washings for proper disposal.

1. 5-Bromo-2-chlorobenzoic acid CAS 21739-92-4 is harmful if swallowed, inhaled as dust, or in contact with skin. It causes skin irritation and serious eye damage.
2. 5-Bromo-2-Chlorobenzoic acid is combustible and may emit toxic fumes (hydrogen chloride, hydrogen bromide, carbon oxides) when heated to decomposition.
3. Always consult the official 5-bromo-2-chlorobenzoic acid Safety Data Sheet (SDS) for comprehensive hazard, handling, toxicological, and regulatory information.
