Applications
3,5-Dibromosalicylaldehyde is a high-active disubstituted aromatic aldehyde intermediate, bearing hydroxyl, aldehyde and two bromine atoms on benzene ring. It readily undergoes condensation, cyclization, substitution and cross-coupling reactions, widely used as key building block in organic synthesis for constructing Schiff bases, fused heterocyclic compounds and multi-substituted aromatic derivatives.
In pharmaceutical industry, it is an important raw material for synthesizing antibacterial, anti-inflammatory, antioxidant and antitumor drug intermediates, also used in the preparation of metal complex catalysts and enzyme inhibitors. In agrochemicals, it is applied to manufacture high-efficiency fungicides, bactericides and plant protection intermediates. It is also commonly used in dye synthesis, organic photoelectric materials, chelating agents, analytical reagents and laboratory custom fine chemical synthesis.
Safety Information
This compound is irritating to skin, eyes and respiratory tract. Direct skin contact may cause redness, itching and mild inflammatory reaction; long-term exposure may induce skin sensitization and allergy. Eye contact will lead to severe stinging, conjunctival congestion and tearing, requiring immediate thorough rinsing with plenty of running water. Inhalation of dust irritates respiratory mucosa, causing throat dryness, cough and chest discomfort. Accidental ingestion may trigger mild gastrointestinal symptoms such as nausea and abdominal distension.
Harmful to aquatic organisms, prohibited from direct discharge into water and soil. Operate in ventilated fume hood, wear nitrile gloves, chemical goggles and dust mask during handling. Keep away from high temperature, open flame and strong oxidants. Store sealed, dry and away from light. Waste and packaging shall be disposed per hazardous chemical waste regulations to avoid environmental pollution and health risks.
