18708-86-6 Usage

General Description

CHLORFENVINPHOS is an organophosphate insecticide commonly used in agricultural settings to control a wide range of pest insects. It is known to be highly toxic to both humans and animals, and exposure to this chemical can lead to a range of negative health effects, including nausea, vomiting, diarrhea, dizziness, and respiratory issues. CHLORFENVINPHOS works by inhibiting the activity of the enzyme acetylcholinesterase, which is essential for the proper functioning of the nervous system. Due to its toxicity and potential for causing harm, its use has been restricted and banned in some countries. However, it is still used in certain parts of the world and is a subject of concern due to its potential negative impact on human and environmental health.

Check Digit Verification of cas no

The CAS Registry Mumber 18708-86-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,0 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18708-86:
(7*1)+(6*8)+(5*7)+(4*0)+(3*8)+(2*8)+(1*6)=136
136 % 10 = 6
So 18708-86-6 is a valid CAS Registry Number.

Preparation of carbon-14 labeled organophosphate pesticides: Chlorfenvinphos

Fudala, Louise,Lewin, Anita H.

, p. 261 - 266 (1998)

Synthesis of [vinyl-14C]chlorfenvinphos, utilizing [14C]iodomethane as the source of the label, was accomplished in 28% radiochemical yield by the methylation of 2,4-dichlorobenzoyl chloride, chlorination of the resulting [14C]-2,4-dichloroacetophenone, and condensation of the product with triethylphosphite. The product, isolated as a mixture of E and Z isomere (3.6 and 96.3%, respectively), was obtained in >99% purity and had specific activity 20 mCl/mmol.
