115-26-4 Usage
Chemical Properties
Colorless liquid; fishy odor; bp 86 °C(186.8 °F) at 15 torr; vapor pressure 0.36 at25 °C (77 °F) (Martin 1974); specific gravity 1.115 at 20 °C (68 °F); oxidized slowly instrong oxidizing agents; decomposes in presence of chlorine; readily soluble in water andin most organic solvents.
Uses
Insecticide; acaricide.
General Description
Colorless liquid with a fishy odor. Used as an insecticide; is neither produced nor used in the U.S. Not registered as a pesticide in the U.S.
Reactivity Profile
Highly toxic fumes are given off upon decomposition of DIMEFOX with heat. Container may explode in heat of fire. Decomposes rapidly in the presence of chlorine. Oxidizes slowly in strong oxidizing agents. [EPA, 1998]. Organophosphates 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
Different sources of media describe the Health Hazard of 115-26-4 differently. You can refer to the following data:
1. DIMEFOX is extremely toxic; the probable oral lethal dose (human) is 5-50 mg/kg, or 7 drops to 1 teaspoonful for a 150-lb. person. Death may occur from respiratory arrest. Hazards of vapor toxicity are high.
2. Although structural feature in the moleculevaries from most other organophosphoruspesticides, the toxic actions are similarto parathion and other phosphate esters.Extremely toxic by all routes of exposure;cholinesterase inhibitor; can present a serious inhalation hazard, if spilled, due to relatively high vapor pressure; exhibits acute,delayed, and chronic effects; symptoms ofcholinergic effects similar to those of otherorganophosphates; death can result from res-piratory arrest; ingestion of 0.3–2 g could befatal to adult human.LD50 oral (rat): 1.0 mg/kg.
Fire Hazard
(Non-Specific -- Insecticide, Liquid, Poisonous, n.o.s.) Highly toxic fumes are given off upon decomposition with heat. Container may explode in heat of fire. Decomposes rapidly in the presence of chlorine. Oxidizes slowly in strong oxidizing agents.
Safety Profile
Poison by ingestion, skin contact,intraperitoneal, subcutaneous, and intravenous routes.When heated to decomposition it emits very toxic fumesof F-, NOx, and POx.
Check Digit Verification of cas no
The CAS Registry Mumber 115-26-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 115-26:
(5*1)+(4*1)+(3*5)+(2*2)+(1*6)=34
34 % 10 = 4
So 115-26-4 is a valid CAS Registry Number.

Fluorination of organochlorophosphorus compounds with alkali metal salts of perfluorinated complex anions. Part 2
Farooq, Omar
, p. 81 - 84 (2000)
Alkali metal salts of perfluorinated complex anions were used to fluorinate a few selected organochlorophosphorus compounds in the presence and absence of a multifunctional etheral solvent. Together with oxidative products, low to moderate yields of the desired monofluorinated products were obtained.
