Description
Tricyclazole is a triazolobenzothiazole fungicide, specifically a [1,2,4]triazolo[3,4-b][1,3]benzothiazole substituted at position 5 by a methyl group. It exhibits properties such as a log Kow of 1.4, solubility in water at 25°C (1.6 g/L), acetone (10.4 g/L), methanol (25 g/L), and xylene (2.1 g/L), and is stable at 52°C with relative stability to ultraviolet light. Tricyclazole is primarily used for the control of rice blast and is not approved for use within the European Union.
Uses
Used in Agriculture:
Tricyclazole is used as a fungicide for the control of rice blast fungus in both transplanted and direct-seeded rice. Its application helps protect crops from the damaging effects of the fungus, ensuring a higher yield and better quality of rice.
Metabolism
Animals: Rapid and extensive metabolism.
Plants: The principal metabolite is the hydroxymethyl
analog. Soil/Environment: Kd 4 (loamy sand, pH 6.5, 1.5%
o.m.), 45 (loam, pH 5.7, 3.1% o.m.), 21 (clay loam, pH 7.4,
1.9% o.m.), 22 (silty clay loam, pH 5.7, 4.1% o.m.).

Check Digit Verification of cas no
The CAS Registry Mumber 41814-78-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,8,1 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 41814-78:
(7*4)+(6*1)+(5*8)+(4*1)+(3*4)+(2*7)+(1*8)=112
112 % 10 = 2
So 41814-78-2 is a valid CAS Registry Number.

Page/Page column 7-9, (2010/02/07)
An improved efficient environmentally safe process for the production of Tricyclazole useful fungicide for rice blast in aqueous slurry form, which involves reacting Hydrazino intermediate (2) obtained from amino compound (1) with formic acid in the presence of p- Toluene sulphonic acid catalyst in two step reaction is discussed. In reaction step (a) 2- Hydrazine -4- methyl benzothiazole (2) is prepared by reacting Amino compound (1) with 80 % Hydrazine Hydrate in the presence of MEG and Hydrochloric acid at 100- 120 ° C. In step (b) the condensation process with 85-98 % formic acid is carried in the presence of acid promotor catalyst at 100- 140° C. The final product is isolated in aqueous slurry form by dumping solvent free molton stirrable mass in precooled water.
