Halquinol (CAS No. 8067-69-4) is a synthetic antimicrobial compound composed of a mixture of chlorinated hydroxyquinoline derivatives, primarily used as a veterinary feed additive and growth promoter in animal nutrition. It belongs to the quinoline class of compounds and exhibits broad-spectrum antibacterial, antifungal, and antiprotozoal activities. Halquinol is particularly valued in livestock and poultry production for its ability to improve feed efficiency, promote growth, and control gastrointestinal disorders.
Mechanism of Action:
Halquinol exerts its antimicrobial effects through multiple mechanisms:
Metal Ion Chelation: Forms complexes with essential metal ions (iron, copper, zinc), depriving microorganisms of these vital nutrients required for growth and metabolism.
Cell Membrane Disruption: Interferes with fungal cell wall synthesis and bacterial cell membrane integrity.
Gastrointestinal Effects: Reduces gastrointestinal motility in animals, prolonging feed transit time and enhancing nutrient absorption efficiency.
Broad-Spectrum Activity: Effective against Gram-positive and Gram-negative bacteria, fungi (including Candida and Aspergillus species), and certain protozoa.
Benefits & Advantages:
For Animal Health & Production:
Improved Growth Performance: Increases average daily gain and feed conversion efficiency
Reduced Mortality: Controls enteric diseases and reduces mortality rates
Enhanced Nutrient Absorption: Prolongs intestinal transit time, improving nutrient utilization
Broad-Spectrum Protection: Effective against multiple pathogens with low resistance development
For Feed Manufacturers:
Stable in Feed: Maintains efficacy during feed processing and storage
Compatible with Other Additives: Can be used with vitamins, minerals, and other feed ingredients
Cost-Effective: Improves production economics through better feed efficiency.
Storage Conditions: Store in tightly closed containers, protected from light and moisture at room temperature. Shelf life: 24 months under proper storage conditions.
