Phenothrin Chemical Properties,Usage,Production

Description

Phenothrin is pale yellow to yellow–brown clear liquid with a faint characteristic odor.

Chemical Properties

Pale yellow to yellow-brown liquid

Uses

ectoparasiticide

Uses

Phenothrin is an insecticide used in commercial and industrial settings, medical institutions, and other institutional settings. Phenothrin is formulated for use in greenhouses, homes, and gardens, and in recreational areas. Additionally, phenothrin has public health uses, specifically its use for vector control for mosquitoes both indoor and outdoor.

Uses

Insecticide.

Definition

ChEBI: Phenothrin is a cyclopropanecarboxylate ester. It has a role as a pyrethroid ester insecticide. It is functionally related to a chrysanthemic acid.

General Description

Pale yellow to yellow-brown liquid. Non corrosive. Used as an insecticide.

Air & Water Reactions

Insoluble in water. Hydrolyzed by alkalis.

Reactivity Profile

A pyrethroid derivative.

Agricultural Uses

Insecticide: Used world-wide to control household insects and to protect stored grain. It is frequently formulated withother insecticides and is formulated in a number of carriers (aerosols, oil, dust, emulsifiable concentrates), and in powders, shampoos and lotion.

Trade name

FORTE®; MULTICIDE-2154®; OMS 1809®; OMS 1810®; PHENOXYTHRIN®; PT-515; S-2539®; SUMETHRIN®; SUMITHRIN®; WELLCIDE® Note: The U.S. EPA currently lists 724 active or canceled products, 242 of which are active. Most products are for residential flying insect control, e.g., fleas, wasps, flies, mosquitoes. Not approved for use in EU countries[115]. Registered for use in the U.S. and Canada

Safety Profile

Low toxicity by ingestion and skin contact. When heated to decomposition it emits acrid smoke and irritating vapors.

Synthesis

Commercially available chrysanthemic acid (231) was converted to the corresponding acyl chloride 232 in 99% yield. Further condensation with 3- phenoxyphenyl methanol (233) in pyridine provided phenothrin (XXVIII) in 96% yield.

Potential Exposure

d-Phenenothrin is a pyrethroid insecticide whic is used world-wide to control household insects and to protect stored grain. It is frequently formulated with other insecticides and is formulated in a number of carriers (aerosols, oil, dust, emulsifiable concentrates), and in powders, shampoos and lotion.

Environmental Fate

Routes and pathways relevant physicochemical Phenothrin is a pale yellow to brown clear liquid with a faint characteristic odor. Its reported solubility is very low<9.7 mg l^-1 at 25 °C. It has a low vapor pressure of 1.43 × 10^-7 mmHg at 21 C, and a calculated Henry’s Law constant of 6.80  10^-6 atm-m3 mol^-1. The octanol/water partition coefficient for phenothrin is 1.03 × 106 (log Kow ? 6.01 at 20 °C).

UN3349 Pyrethroid pesticide, solid toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous material. UN3352 Pyrethroid pesticide, liquid toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Toxicity evaluation

Acute oral LD₅₀ for rats: >5,000 mg/kg

Incompatibilities

Keep away from alkaline materials. May react violently with strong oxidizers, bromine, 90% hydrogen peroxide, phosphorus trichloride, silver powders or dust. Incompatible with silver compounds. Mixture with some silver compounds forms explosive salts of silver oxalate. Compounds of the carboxyl 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 compounds (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).

Waste Disposal

Incineration would be an effective disposal procedure where permitted. If an efficient incinerator is not available, the product should be mixed with large amounts of combustible material and contact with the smoke should be avoided. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers
