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:
3(2H)-Isthiazolone is composed
of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and
2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect
of
3(2H)-Isthiazolone is carried
out through breaking the bond between bacteria and algae
protein. When contacted with microbes,
3(2H)-Isthiazolone can quickly inhibit their growth,
thus leading to death of these microbes.
3(2H)-Isthiazolone 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.
3(2H)-Isthiazolone can mix
with chlorine and most cation, anion, and non-ionic
surfactants. When used at high dosage, its biosludge
stripping effect is excellent.
3(2H)-Isthiazolone 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.
