4-bromo-3-methylbenzoic Acid CAS 7697-28-1

1. 4-Bromo-3-methylbenzoic acid is primarily used as an intermediate in organic synthesis, particularly in cross-coupling reactions (e.g., Suzuki, Heck) to introduce bromo- and carboxyl-functionalized aromatic motifs into pharmaceuticals, agrochemicals, and materials.
2. 4-Bromo-3-methylbenzoic acid CAS 7697-28-1 serves as a building block for heterocyclic compounds, dyes, and liquid crystals, leveraging its reactive bromine and carboxylic acid groups for further transformations.
3. 4-Bromo-3-methylbenzoic acid functions as a precursor for specialty polymers, UV absorbers, and corrosion inhibitors in industrial applications.

1. Store 4-bromo-3-methylbenzoic acid in a cool, dry, well-ventilated area, protected from light and moisture, in tightly sealed, corrosion-resistant containers (e.g., glass or certain plastics).
2. Keep 4-bromo-3-methylbenzoic acid CAS 7697-28-1 separate from strong oxidizing agents, strong bases, and reactive metals to prevent hazardous decomposition or violent reactions.
3. Handle 4-bromo-3-methylbenzoic acid with care using non-sparking tools and grounded equipment; ensure containers are clearly labeled and stored in a dedicated, secure area.

1. Immediately isolate the spill area, eliminate all ignition sources, and ensure forced ventilation; avoid direct contact and prevent the material from entering drains or soil.
2. Carefully neutralize spilled 4-bromo-3-methylbenzoic acid CAS 7697-28-1 with a suitable alkaline substance (e.g., sodium bicarbonate) if trained to do so safely, then absorb with inert materials (e.g., sand, vermiculite).
3. Collect neutralized residue and contaminated absorbents into sealed, labeled containers for disposal as hazardous chemical waste; clean the surface thoroughly with water and dispose of all waste according to hazardous material regulations.

1. 4-Bromo-3-methylbenzoic acid is corrosive and may cause severe skin burns, eye damage, and respiratory tract irritation upon contact or inhalation of dust/mists.
2. 4-Bromo-3-methylbenzoic acid CAS 7697-28-1 is harmful if swallowed or inhaled, and repeated or prolonged exposure may cause damage to specific organs; it may release toxic bromine vapors upon heating or decomposition.
3. Always handle 4-bromo-3-methylbenzoic acid in a certified fume hood or with adequate local exhaust, wearing appropriate PPE including chemical-resistant gloves, face shield, chemical goggles, and protective clothing.
