Isothiazolinone, CMIT/MIT

CAS No.: 26172-55-4, 2682-20-4

Molecular Weight: 115.16

Structural Formula:




Isothiazolinone (CMIT/MIT) consists of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and 2-methyl-4-thiazoline-3-ketone (MI). The actual bactericidal effect of isothiazolinone is carried out by means of breaking the bond between bacterias and also algae proteins.

The moment approached together with microbes, Isothiazolinone (CMIT/MIT) can quickly prevent their growth. Therefore, it results in the actual death of those microbes. Isothiazolinone features powerful inhibition and biocidal effects on regular microorganisms, fungi, and also alga. And it has lots of advantages. For example high biocidal efficiency, excellent degradation, zero residual, safety in operation, great compatibleness, superior stabilization, and affordability.

Isothiazolinone (CMIT/MIT) is able to combine together with chlorine and most cation, anion, and non-ionic surfactants. When applied with a large dosage, its biosludge stripping effect is fantastic.

When used as a sludge stripper for grade II, the dosage of Isothiazolinone 150-300mg/L is preferred.

When used as a biocide, the dosage of 80-100mg/L is preferred and charges every 3-7 days.

No used together with oxidative fungicidal such as chlorine. And not used in cooling water systems containing sulfur.

When used together with a quaternary amine, the effect will be better.

When used as an industrial fungicide, the dosage of Isothiazolinone 0.05-0.4% is preferred.


Isothiazolinone (CMIT/MIT) is a type of fungicidal along with many properties. Such as broad-spectrum, high efficiency, low toxicity, and non-oxidative. Isothiazolinone (CMIT/MIT) may be the best biocidal in the industrial circulating cool water system. And also in wastewater treatment in the oilfield, papermaking, pesticide, cutting oil, leather, detergent, and cosmetics, etc..
