18691-97-9 Usage

Chemical Properties

White crystalline solid; melts at 120°C(248°F); insoluble in water [~59 ppm at20°C (68°F)], soluble in organic solvents.

Uses

Different sources of media describe the Uses of 18691-97-9 differently. You can refer to the following data:
1. Methabenzthiazuron is a benzothiazole and urea based herbicide used to control a spectrum of broad-leaved weeds and grasses crops. Methabenzthiazuron works via the inhibition of photosynthetic electron transport chain.
2. Methabenzthiazuron is a benzothiazole and urea based herbicide used to control a spectrum of broad-leaved weeds and grasses crops. Methabenzthiazuron works via the inhibition of photosynthetic electro n transport chain.

Health Hazard

Gupta and Singh (1985) investigated thetoxicity of tribunil in calves. Animals treatedwith 500 mg/kg orally developed toxicityin 36–48 hours. The symptoms includedincrease in body temperature, depression,and a progressive decrease in respiration rateand pulse rate. Necropsy findings in animalsthat died showed congestion of the lungs.Other organs affected were liver, kidney,urinary bladder, spleen, heart, and brain.A 75-mg/kg dose produced toxicity after2–3 weeks.

Metabolic pathway

When methabenzthiazuron is presowing applied to the soil of pea fields, three degradation products are detected as (2-benzothiazoyl)urea, 2- (methylamino)benzothiazole and 2- aminobenzothiazole. The latter two amines represent a majority of the soil bound residues.

Check Digit Verification of cas no

The CAS Registry Mumber 18691-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,9 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18691-97:
(7*1)+(6*8)+(5*6)+(4*9)+(3*1)+(2*9)+(1*7)=149
149 % 10 = 9
So 18691-97-9 is a valid CAS Registry Number.
