OIT 2-n-octyl-4-isothiazolin-3-one cas 26530-20-1 for Biocides1

The production process of octylisothiazolinone is prepared by cyclization reaction of di-n-octyldipropylamide, and the reaction conditions require strict control of temperature and catalyst ratio. In industrial production, multi-stage distillation purification technology is used to ensure that the purity of the finished product reaches over 99%. The by-products meet the environmental emission standards after neutralization treatment.The chemical name of octylisothiazolinone (OIT) is N-octyl-4-isothiazolin-3-one, with a CAS number of 26530-20-1 and a molecular formula of C11H19NOS. This substance is a light yellow to brownish yellow liquid or crystal with broad-spectrum antibacterial properties, showing efficient killing effects on microorganisms such as mold, yeast, and bacteria. As a non formaldehyde releasing dry film mold inhibitor, it is suitable for a pH range of 4.0-9.0, has good thermal stability, and can be naturally degraded. Mainly used in industrial fields such as coatings, plastics, leather, ink, etc., replacing traditional toxic preservatives.
