Cov Ntawv Thov
1. Tseem ceeb intermediate nyob rau pyrethroid synthesis
Chrysanthem acid yog lub tsev tseem ceeb thaiv rau cov hluavtaws ntawm hluavtaws pyrethroids, uas tau siv dav cov qauv tshuaj tua kab tom qab ntuj pyrethrins.
Nws tsim cov acid tiv thaiv nyob rau hauv pyrethroid esters zoo li permethrin, cypermerrin, thiab deltamethrin.
2. Agnojical kev lag luam
Siv nyob rau hauv kev tsim cov tshuaj dav dav siv tau rau ntau yam ntawm cov kab ua liaj ua teb nrog rau cov neeg tsis zoo, npauj, kab thiab yoov tshaj cum.
Cov tshuaj tua kab no nthuav tawm nrawm knockdown kev txiav txim thiab lowammalian toxicity, txhim kho qoob loo tiv thaiv.
3. Kev tshawb fawb tshuaj lom neeg ua haujlwm
Muaj nuj nqis nyob rau hauv cov organic synthesis thiab cov kev tshawb fawb ntawm cov nplhaib sib txawv vim nws lub nplhaib cyclopopnane nplhaib thiab ntau yam isomers.
Siv los tshawb cov qauv-kev ua haujlwm sib raug zoo (SAR) hauv kev ua tshuaj tua kab tsuag.
Cov txiaj ntsig
✅ Qhov tseem ceeb rau Pyrethroid Cov Tshuaj Txhuam Kab Mob
Muab cov chiral cycloprorane acid moiety, tseem ceeb rau txoj kev ua yeeb yam ntawm pyrethroids.
Pab tsim muaj zog, ruaj khov, thiab photostable tshuaj tua kab.
Selective Toxicity
Thaum siv nyob rau hauv pyrethroid esters, qhov tshwm sim cov kev lom zem yog mob heev rau cov kab tab sis muaj kev nyab xeeb rau tib neeg thiab tsiaj txhu, ua liaj ua teb, thiab siv tsiaj txhu siv kho tsiaj.
✅ Muaj ib puag ncig ib puag ncig tsis tu ncua
Chrysanthem acid-raws pyrethroids feem ntau tawg sai sai nyob rau hauv ib puag ncig piv txwv rau organophphathaates lossis orgoclorines.
In txhawb nqa kev tswj hwm kev tua kab (IPM)
Pyrethroids muab tau los ntawm chrysanthem acid tau sib xws nrog IPM cov tswv yim, muab tshuaj tua kab kom zoo nrog txo cov tshuaj thauj khoom.
Tag
Chrysanthemic acid (CAS 15641-5841-5841-5841-5841-5841-5841 yog qhov tseem ceeb ntawm cov hluavtaws ntawm cov hluavtaws ntawm cov hluavtaws, ua cov tshuaj acid feem ntau ntawm cov tshuaj tua hluav taws xob siab. Nws cov qauv tshwj xeeb ua rau kev txhim kho kev nyab xeeb, kev ua yeeb yam nrawm, thiab txiav txim siab muaj tshuaj tua kab. Raws li xws li, nws plays lub luag hauj lwm tseem ceeb hauv kev ua liaj ua teb niaj hnub no thiab kev tswj hwm kev noj qab haus huv rau pej xeem.
