152-16-9 Usage
Description
Schradan, also known as octamethyl pyrophosphoramide (OMPA) or bis[bisdimethylaminophosphonous] anhydride (Pestox III), is a dark brown viscous liquid that is miscible with water and soluble in most organic solvents. It is a weak inhibitor of cholinesterases in vitro but is metabolized to a strong inhibitor in vivo. Schradan is not hydrolyzed by alkalies or water but is hydrolyzed by acids.
Uses
Used in Agriculture:
Schradan is used as a systemic insecticide for plants, providing protection against insects that feed on the plants. It is absorbed by the plants without causing significant harm, and insects feeding on the treated plants are incapacitated.
Used in Pest Control:
Schradan is also used as an acaricide, helping to control and manage populations of mites and ticks in various settings. However,
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.
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
Potential Exposure
Material is used as a systemic insecticide
for plants and as an acaricide. Not registered as a
pesticide in the United States.
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.
Check Digit Verification of cas no
The CAS Registry Mumber 152-16-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,5 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 152-16:
(5*1)+(4*5)+(3*2)+(2*1)+(1*6)=39
39 % 10 = 9
So 152-16-9 is a valid CAS Registry Number.

Alkyl 4-[o-(substituted methyleneamino)phenyl]-3-thioallophanates
-
, (2008/06/13)
Various alkyl 4-[o-(substituted methyleneamino)phenyl] 3-thioallophanates are useful as fungicides and mite ovicides. The compounds are prepared by reacting alkyl 4-(o-aminophenyl)-3-thioallophanates with aldehydes or trialkyl orthoformates. Some of the compounds are prepared by further reacting the reaction product of an alkyl 4-(o-aminophenyl)-3-thioallophanate and a trialkyl orthoformate with a primary or secondary amine. Exemplary species are methyl 4-[o-(o-fluorobenzylideneamino)phenyl]-3-thioallophanate, methyl 4-[o-(4-methylbenzylideneamino)phenyl]-3-thioallophanate and methyl 4-[o-(2-furfurylideneamino)phenyl]-3-thioallophanate.
