Used as a highly effective biocide in industrial water treatment systems, particularly in oilfield operations and metalworking fluids. It controls bacterial and fungal growth, preventing microbial-induced corrosion and spoilage. Its stability under high temperatures and harsh pH conditions makes it suitable for downhole applications in oil and gas extraction. Also employed in latex emulsions and paint formulations to extend shelf life by inhibiting microbial contamination during storage. The compound slowly releases trichloromethyl groups, enhancing its long-term antimicrobial performance.
