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].

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).
Shipping
UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required. 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
Check Digit Verification of cas no
The CAS Registry Mumber 26002-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,0,0 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 26002-80:
(7*2)+(6*6)+(5*0)+(4*0)+(3*2)+(2*8)+(1*0)=72
72 % 10 = 2
So 26002-80-2 is a valid CAS Registry Number.

Cobalt-Catalyzed Reductive Dimethylcyclopropanation of 1,3-Dienes
Werth, Jacob,Uyeda, Christopher
, p. 13902 - 13906 (2018/10/02)
Dimethylcyclopropanes are valuable synthetic targets that are challenging to access in high yield using Zn carbenoid reagents. Herein, we describe a cobalt-catalyzed variant of the Simmons–Smith reaction that enables the efficient dimethylcyclopropanation of 1,3-dienes using a Me2CCl2/Zn reagent mixture. The reactions proceed with high regioselectivity based on the substitution pattern of the 1,3-diene. The products are vinylcyclopropanes, which serve as substrates for transition-metal-catalyzed ring-opening reactions, including 1,3-rearrangement and [5+2] cycloaddition. Preliminary studies indicate that moderately activated monoalkenes are also amenable to dimethylcyclopropanation under the conditions of cobalt catalysis.

Monoclonal antibodies to synthetic pyrethroids and method for detecting the same
-
, (2008/06/13)
Methods are described for making specific monoclonal antibodies which may be used in a sensitive immunoassay for detection of synthetic pyrethroids in foods and environmental samples. Appropriate sample preparation and enzyme amplification of the immunoassay for this widely-used class of pesticides permits detection at low levels in laboratory and field tested samples.
