Isothiazolinones
(CIT/MIT)
【CAS】26172-55-4，2682-20-4
Molecular Formula：C21H38NCl Molecular weight: 115.16
Structure:
2-methyl-4-thiazoline-3-ketone 5-chloro- methyl-4-thiazoline-3-ketone
Properties and Usage:
Isothiazolinones is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and 2-methyl-4-
thiazoline-3-ketone (MI). The bactericidal effect of Isothiazolinones is carried out through breaking
the bond between bacteria and algae protein. When contacted with microbes, Isothiazolinones can
quickly inhibit their growth, thus leading to death of these microbes. Isothiazolinones has strong
inhibition and biocidal effects on ordinary bacteria, fungi and alga, and has many advantages such as
high biocidal efficiency, good degradation, no residual, safety in operation, good compatibleness,
good stabilization, low cost in operation. Isothiazolinones can mix with chlorine and most cation,
anion, and non-ionic surfactants. When used at high dosage, its biosludge stripping effect is
excellent. Isothiazolinones is a kind of fungicidal with properties of broad spectrum, high efficiency,
low toxicity and non-oxidative, it is the ideal biocidal in industrial circulating cool water system and in
wastewater treatment
in oilfield, papermaking, pesticide, cutting oil, leather, detergent and
cosmetics etc.

Using method:
When used as sludge stripper for grade II, the dosage of 150-300mg/L is preferred, when used as
boicide, the dosage of 80-100mg/L is preferred, and charges every 3-7 days. No used together with
oxidative fungicidal such as chlorine, and no used in cooling water system containing sulfur. When
used together with quaternary amine, the effect will be better. When used as industrial fungicide,
the dosage of 0.05-0.4% is preferred.
