General Description
Dark brown viscous liquid. Used as an insecticide and as an acaricide. Not registered as a pesticide in the U.S.
Reactivity Profile
Organophosphates, such as SCHRADAN, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Health Hazard
Extremely toxic; probable oral lethal dose in humans is 5-50 mg/kg, between 7 drops and 1 teaspoonful for a 150 lb. person. It is highly toxic when inhaled. Material is a cholinesterase inhibitor. It is similar in action to other organophosphorous pesticides in its toxicity. It is slightly less toxic than parathion. Gastrointestinal, neurologic and respiratory symptoms may accompany poisoning with SCHRADAN. High doses may cause a toxic psychosis similar to acute alcoholism. Persons taking phenobarbital and phenaglycodol together, glutethimide, chlorpromazine hydrochloride, or meprobamate may be at greater risk. These drugs appear to enhance the toxicity of the material markedly.
Fire Hazard
When heated to decomposition, SCHRADAN can emit highly toxic fumes of oxides of phosphorus. Decomposes when mixed with acid. Hydrolyzed under acid conditions to dimethylamine and orthophosphoric acid.
Potential Exposure
Material is used as a systemic insecticide
for plants and as an acaricide. Not registered as a
pesticide in the United States.
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 immediately
with soap and water. Speed in removing material from skin
is of extreme importance. Shampoo hair promptly if contaminated.
Seek medical attention immediately. If this
chemical has been inhaled, remove from exposure, begin
rescue breathing (using universal precautions, 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 quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Obtain authorization and/or further instructions from the
local hospital for administration of an antidote or performance
of other invasive procedures.
Shipping
UN3018 Organophosphorus pesticides, liquid,
toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
Organophosphates are susceptible to formation
of highly toxic and flammable phosphine gas in the
presence of strong reducing agents such as hydrides and
active metals. Partial oxidation by oxidizing agents may
result in the release of toxic phosphorus oxides. Acids.

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. 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 governing storage, transportation,
treatment, and waste disposal.
Definition
ChEBI: Schradan is a phosphorodiamide.
Production Methods
Schradan is commercially produced via a process that involves the reaction of dimethylamine with phosphorus oxychloride, followed by condensation to form the pyrophosphoramide structure.
Mechanism of action
Systemic. Acetylcholinesterase (AchE) inhibitor.
Safety Profile
Poison by ingestion, inhalation,skin contact, intraperitoneal, intravenous, subcutaneous,and ocular routes. Human systemic effects by ingestion: acholinesterase inhibitor. Has been found to inhibitperipheral cholinesterase without pronounced effects o
storage
