741-58-2 Usage
Description
Bensulide is a selective pre-emergence herbicide used primarily for controlling annual grasses and broadleaf weeds in various agricultural crops. It is available as a colorless liquid with a slight odor, insoluble in water but soluble in kerosene and xylene. Bensulide can also exist as an amber viscous liquid or form colorless or white crystalline solid below 34.4°C. It is combustible, and the commercial product is available as an emulsifiable concentrate.
Uses
Used in Agricultural Industry:
Bensulide is used as a herbicide for preemergent control of annual grasses and broadleaf weeds in agricultural crops such as carrots, fruiting vegetables, leafy vegetables (mostly head lettuce), dry bulb vegetables (onions), cucurbits (mostly melons), and cole crops (cauliflower, cabbage, broccoli, broccolini, and broccoflower). It is also used on field-grown herbaceous plants and field-grown bulbs.
Used in Turf and Golf Courses:
Bensulide is used as a herbicide to control bluegrass, crabgrass, and other annual grasses and broadleaf weeds in agriculture crops, cotton, and turf. It is widely used on golf courses and home lawns, targeting weeds such as barnyardgrass, burning nettle, and canarygrass.
Outdoor Homeowner and Professional Use:
Products containing bensulide are intended for outdoor homeowner use on lawns and ornamentals, as well as application by professional lawn care operators to lawns, ornamentals, parks, and recreation areas.
Note: Bensulide is not approved for use in EU countries.

Potential Exposure
A selective preemergence organophosphate
herbicide used to control bluegrass, crabgrass and
other annual grasses and broadleaf weed s in agriculture
crops, cotton and turf. It is widely used on golf courses and
home lawns. Target weeds also include barnyard grass,
burning nettle, and canary grass.
Carcinogenicity
Bensulide was given in the diet
for 104 weeks to rats at levels to achieve doses of 0, 1, 15, or
60 mg/kg/day . No cholinergic signs were observed at
any dose. Increased absolute liver weights accompanied by
mild histopathological changes (hepatocyte vacuolation and
eosinophilic foci) occurred at 60 mg/kg/day, but there was no
evidence of carcinogenic potential.
Bensulide was given in the diet for 78 weeks to mice at
levels to achieve 0, 1, 50, or 200 mg/kg/day . Survival
rates, clinical observations, and hematological parameters
were unaffected at all doses. Decreased overall body weight
gains, increased absolute and relative liver weights accompanied
by histopathological changes (pale foci, cell atypia,
and cell foci) occurred at 200 mg/kg/day (males only).
Overall body weight gain was also reduced in males at
50 mg/kg/day, but there was no evidence of carcinogenic
potential.
Shipping
UN3018 Organophosphorus pesticides, liquid,
toxic, Hazard Class: 6.1; Labels: 6.1—Poisonous materials.
UN3077 Environmentally hazardous substances, solid, n.o.s.,
Hazard class: 9; Labels: 9—Miscellaneous hazardous material,
Technical Name Required.
Incompatibilities
Incompatible with oxidizers; chlorates
nitrates, peroxides. Decomposes slowly in light and strong
UV. Corrosive to copper, aluminum, magnesium, zinc.
Slowly hydrolyzes in water, releasing ammonia gas and
forming acetate salts. In the presence of strong reducing
agents such as hydrides, organophosphates form highly toxic
and flammable phosphine gas. Contact with oxidizers can
cause the release of toxic oxides of phosphorus. Stable @
80 C for 50 hours; decomposes @ 200° C in 18 40 hours.
Waste Disposal
Destruction by alkali hydrolysis
or incineration. Containers must be disposed of properly
by following package label directions or by contacting your
local or federal environmental control agency, or by contacting
your regional EPA office.
Check Digit Verification of cas no
The CAS Registry Mumber 741-58-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,4 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 741-58:
(5*7)+(4*4)+(3*1)+(2*5)+(1*8)=72
72 % 10 = 2
So 741-58-2 is a valid CAS Registry Number.
