Used primarily as a preservative and biocide in water-based systems, this compound is effective against a broad spectrum of microorganisms including bacteria, fungi, and yeast. It is commonly applied in industrial water treatment, metalworking fluids, and latex emulsions to prevent microbial degradation and spoilage. Its stability across a wide pH range and effectiveness at low concentrations make it suitable for use in coatings, adhesives, and pigment slurries. The compound releases chlorine slowly, providing prolonged antimicrobial activity, and is often chosen where long-term preservation and resistance to microbial contamination are critical.
