Hazard Information | Back Directory | [General Description]
White solid. Used as a selective herbicide. | [Reactivity Profile]
3,5-DICHLORO-N-(1,1-DIMETHYL-2-PROPYNYL)BENZAMIDE is a chlorinated amide. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). | [Potential Exposure]
A potential danger to those involved
in the manufacture, formulation and application of this
selective herbicide. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts
the skin, remove contaminated clothing and wash immedi-
ately with soap and water. Seek medical attention immedi-
ately. If this chemical has been inhaled, remove from
exposure, begin rescue breathing (using universal precau-
tions, including resuscitation mask) if breathing has
stopped and CPR if heart action has stopped. Transfer
promptly to a medical facility. When this chemical has
been swallowed, get medical attention. Give large quanti-
ties of water and induce vomiting. Do not make an uncon-
scious person vomit. | [Shipping]
UN3077 Environmentally hazardous substances,
solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous haz-
ardous material, Technical Name Required. | [Incompatibilities]
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explo-
sions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides. Compounds of the car-
boxyl group react with all bases, both inorganic and
organic (i.e., amines) releasing substantial heat, water and a
salt that may be harmful. Incompatible with arsenic com-
pounds (releases hydrogen cyanide gas), diazo compounds,
dithiocarbamates, isocyanates, mercaptans, nitrides, and
sulfides (releasing heat, toxic and possibly flammable
gases), thiosulfates and dithionites (releasing hydrogen
sulfate and oxides of sulfur). | [Chemical Properties]

White Solid | [Waste Disposal]
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations govern-
ing storage, transportation, treatment, and waste disposal.
In accordance with 40CFR165, follow recommendations
for the disposal of pesticides and pesticide containers. Must
be disposed properly by following package label directions
or by contacting your local or federal environmental control
agency, or by contacting your regional EPA office. | [Uses]
Herbicide. | [Uses]
Preemergence or postemergence herbicide used to control many perennial and annual
grasses and broad-leaved weeds in ornamental trees and shrubs, forestry, fruits and vegetables | [Uses]
Selective pre-emergence herbicide. | [Definition]
ChEBI: A member of the class of benzamides resulting from the formal condensation of the carboxy group of 3,5-dichlorobenzoic acid with the amino group of 2-methylbut-3-yn-2-amine. It is used as a systemic post-emergent herbicide for the control grass and broadle
f weeds in a wide range of in a wide variety of fruit and root crops. | [Agricultural Uses]
Herbicide: Pronamide is a selective herbicide used either before weeds emerge (pre-emergence), and/or after weeds come up (post-emergence). It controls a wide range of annual and perennial grasses, as well as certain annual broadleaf weeds. It is used primarily on lettuce and alfalfa crops, as well as on blueberries, ornamentals, fruit trees, forage legumes, and on pastures and rangelands. Pronamide is usually incorporated into the soil by cultivation, irrigation, or rain immediately following application. It is available in wettable powder and granular formulations. Registered for use in the U.S. and EU countries. A U.S. EPA restricted Use Pesticide (RUP). | [Trade name]

Biological. In the presence of suspended natural populations from unpolluted aquatic
systems, the second-order microbial transformation rate constant determined in the laboratory was reported to be 5 × 10–14 L/organisms-hour (Steen, 1991).
Soil. The major soil metabolite is 2-(3,5-dichlorophenyl)-4,4-dimethyl-5-methyleneoxazoline. The half-life in soil is approximately 30 days at 25°C (Hartley and Kidd, 1987).
Residual activity in soil is limited to approximately 2–6 months (Hartley and Kidd, 1987).
Chemical/Physical. Emits toxic fumes of nitrogen oxides and chlorine when heated
to decomposition (Sax and Lewis, 1987).
Propyzamide is hydrolyzed to 3,5-dichlorobenzoate by refluxing under strongly acidic
conditions (Humburg et al., 1989). |
