General Description
CHLORPYRIFOS D10 is a chemical compound used as an insecticide primarily for agricultural purposes. It belongs to the class of organophosphate pesticides, which work by disrupting the nervous system of insects, leading to paralysis and eventual death. This specific formulation, CHLORPYRIFOS D10, contains 10% of the active ingredient chlorpyrifos, which has been widely used in the control of a variety of pests including termites, ants, and other insects. However, there have been concerns about its potential toxicity to humans and the environment, leading to regulatory restrictions and bans in some countries. As a result, alternatives to chlorpyrifos-based pesticides are being sought for sustainable pest control practices.
Check Digit Verification of cas no
The CAS Registry Mumber 285138-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,5,1,3 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 285138-81:
(8*2)+(7*8)+(6*5)+(5*1)+(4*3)+(3*8)+(2*8)+(1*1)=160
160 % 10 = 0
So 285138-81-0 is a valid CAS Registry Number.

Stable isotope-labeled chlorpyrifos-d10 and synthesis method thereof
-
Paragraph 0029-0031; 0035, (2020/12/15)
The invention discloses stable isotope-labeled chlorpyrifos-d10 and a synthesis method thereof. The synthesis method includes the steps: making stable isotope labeled ethyl alcohol-d10 as a stable isotope labeling source react with phosphorus pentasulfide to obtain stable isotope-labeled o, o-diethylphosphorothioate, making the stable isotope-labeled o, o-diethylphosphorothioate and 3, 5, 6-trichloro-2-pyridinol sodium salt undergo a condensation reaction to obtain the stable isotope labeled chlorpyrifos-d10 product. The stable isotope labeling raw material used in the method is ethanol-d10, the source is easy to obtain, the price is low, the synthesis process is simple and easy to operate, the product is simple and convenient to separate and purify, the chemical purity and isotope abundance of the obtained product can reach 98% or above, and the related requirements of a standard reagent for quantitatively detecting the chlorpyrifos content are met.
