8-Hydroxyquinoline: A Versatile Compound Driving Innovation Across Industries

ByBNW TEAM

Introduction

In the world of specialty chemicals, few compounds stand out for their versatility and functionality like 8-Hydroxyquinoline (8HQ). Also known as oxine, this organic chemical has earned a prestigious place across multiple industries—from pharmaceuticals and personal care to agriculture and analytical chemistry. At Kajay Remedies, India’s first commercial manufacturer of 8-Hydroxyquinoline, we are proud to deliver high-purity, consistent, and globally trusted formulations that empower innovation worldwide.

This blog explores the properties, applications, and benefits of 8-Hydroxyquinoline, while also highlighting Kajay Remedies’ leadership in this field.

What is 8-Hydroxyquinoline?

8-Hydroxyquinoline is an organic compound belonging to the quinoline group, with the chemical formula C₉H₇NO. What makes it remarkable is its chelating ability—the property to bind strongly with metal ions like copper, iron, and aluminum. This allows it to form stable complexes, making it indispensable in applications where stabilization, preservation, or microbial protection is required.

Key Chemical Properties:

  • Appearance: Off-white to beige-brown crystalline powder
  • Purity: Minimum 99%
  • Moisture Content: 0.5%
  • Chemical Assay: Minimum 98%
  • CAS Number: 148-24-3

Applications of 8-Hydroxyquinoline

1. Hair Dye and Cosmetic Industry

The personal care sector relies heavily on 8HQ, particularly in hair dye formulations.

  • Dye Stabilization: By chelating metal ions present in water or cosmetic bases, 8HQ prevents unwanted reactions, ensuring brighter and longer-lasting colors.
  • Antimicrobial Protection: With natural antibacterial and antifungal properties, it protects hair dye formulations from microbial contamination, extending their shelf life.
  • Consumer Benefit: Safer, more reliable, and vibrant hair dyes that retain their effect longer.

2. Veterinary and Animal Health (Halquinol)

When chlorinated, 8-Hydroxyquinoline transforms into Halquinol, a powerful antimicrobial and antifungal compound.

  • Livestock Health: Used in poultry and swine farming, Halquinol controls bacterial infections caused by coli and Salmonella, two common culprits of diarrhea and growth suppression.
  • Productivity Boost: By improving intestinal health in animals, Halquinol enhances growth rates and overall productivity in animal husbandry.
  • Veterinary Medicine: It is included in feed supplements and medicines to prevent and treat infections, safeguarding animal welfare.

3. Pharmaceutical Industry

In pharmaceuticals, 8-Hydroxyquinoline is a trusted ingredient in several formulations:

  • Topical Antiseptics & Disinfectants: Used in ointments, creams, and sprays to treat skin infections.
  • Chelating Agent for Metal Poisoning: Effective in binding harmful metal ions for medical detoxification.
  • Antifungal & Antibacterial Treatments: Plays a role in treating nail and skin infections.
  • Ophthalmic Preparations: Found in eye drops and ointments to combat microbial eye infections.
  • Dental Products: Included in certain mouthwashes and dental gels to maintain oral hygiene.
  • Pharmaceutical Preservative: Enhances product stability and shelf life by preventing microbial growth.

4. Agriculture and Horticulture

Farmers and horticulturists value 8HQ as both a fungicide and micronutrient carrier.

  • Soil Treatments: Enriches soil with micronutrients while controlling fungal pathogens.
  • Foliar Sprays: Provides protective action against aerial fungal diseases.
  • Seed Treatments: Pre-planting sprays safeguard seedlings from fungal infestations, ensuring healthier germination.
  • Plant Growth: By chelating essential nutrients, it improves plant vigor, yield, and quality.

5. Analytical Chemistry and Environmental Applications

In laboratories and environmental monitoring, 8HQ is widely used as a reagent for metal ion detection.

  • Water Quality Testing: Helps detect trace amounts of heavy metals in water.
  • Environmental Monitoring: Used in qualitative and quantitative analysis of pollutants.
  • Industrial Quality Control: Applied in various industries for testing and maintaining process consistency.
