CAS No. 26172-55-4, 2682-20-4
Molecular weight: 115.16
Structural Formula:
2-methyl-4-thiazoline-3-ketone
5-chloro- methyl-4-thiazoline-3-ketone
Properties:
2-Methyl-3(2H)-Isothiazolone
is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI)
and 2-methyl-4-thiazoline-3-ketone (MI). The bactericidal
effect of
2-Methyl-3(2H)-Isothiazolone is carried out through
breaking the bond between bacteria and algae protein. When
contacted with microbes,
2-Methyl-3(2H)-Isothiazolone
can quickly inhibit their
growth, thus leading to death of these microbes.
2-Methyl-3(2H)-Isothiazolone
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.
2-Methyl-3(2H)-Isothiazolone can mix
with chlorine and most cation, anion, and non-ionic
surfactants. When used at high dosage, its biosludge
stripping effect is excellent.
2-Methyl-3(2H)-Isothiazolone
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..
Specification:
Notes: 2%, 4% and 8% or any concentration can be supplied
on demands.

Usage:
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.
Package and Storage:
