4,5-Dichloro-2-n-octyl-3-isothiazolinone (DCOIT) is a highly effective broad-spectrum biocide widely used in coatings, plastics, and wood preservatives. This compound exhibits a melting point of 40-44°C and predicted boiling point of 322.6±52.0°C. With a density of 1.25±0.1 g/cm³, it demonstrates excellent stability under normal conditions. As a low-toxicity antimicrobial agent, it effectively controls bacteria, fungi and algae in various industrial applications. Storage should be in sealed containers under inert gas (nitrogen/argon) at 2-8°C. Safety precautions include wearing protective equipment due to its irritating properties (GHS Category 2).
