2-Methyl-4-isothiazolin-3-one hydrochloride (CAS 26172-54-3)

2-Methyl-4-isothiazolin-3-one hydrochloride, or MIT hydrochloride, is a potent biocide derived from the isothiazolinone family, recognized for its broad-spectrum antifungal and antimicrobial properties. The compound operates by disrupting critical microbial enzymatic systems, particularly targeting the thiol groups in cysteine residues within enzymes essential for respiratory and metabolic processes. This interaction leads to the inhibition of these key pathways, ultimately causing microbial cell death due to energy production failure. In the realm of research, MIT hydrochloride has been extensively utilized to investigate the biochemical mechanisms of action of isothiazolinones and to study microbial resistance to biocides. These studies are crucial in non-medical fields such as industrial microbiology, where understanding and controlling microbial contamination is essential. Insights gained from research on MIT hydrochloride aid in the development of advanced biocidal formulations for applications in water treatment, paint preservation, and other industries, ensuring product efficacy and longevity by effectively managing microbial growth. Thus, MIT hydrochloride not only serves as a powerful tool in microbial management but also enriches scientific understanding of biocide action and resistance.
