| Nā Code Risk | R25 - He mea ʻawaʻawa inā ʻai ʻia R36/37/38 – Hoʻonanea i ka maka, ka ʻōpū hanu a me ka ʻili. |
| Ka wehewehe palekana | S7/9 - S22 – Mai hanu i ka lepo. S24/25 – Hōʻalo i ka pili ʻana me ka ʻili a me nā maka. S26 – Inā pili me nā maka, e holoi koke me ka wai nui a e ʻimi i ka ʻōlelo aʻo kino. S36/37 – E hoʻohana i nā lole pale kūpono a me nā mīkina lima. S38 – Inā lawa ʻole ka ea, e hoʻohana i nā mea hana hanu kūpono. S45 – Inā loaʻa ka pōʻino a i ʻole ka maikaʻi ʻole, e ʻimi koke i ka ʻōlelo aʻo kino (e hōʻike i ka lepili inā hiki.) S51 – E hoʻohana wale ma nā wahi ʻea maikaʻi. |

Hoʻolauna
He mau mea koʻikoʻi ka pūhui i ka hoʻohui ʻana i ka lāʻau a me ka synthesis pesticide. Hiki ke hoʻohana ʻia ma ke ʻano he waena no ka synthesis o nā pūhui hana biologically. No ka laʻana, hiki ke hoʻohana ʻia e synthesize i nā lāʻau antiviral a me nā pesticides, etc.
Hiki ke hoʻomākaukauʻia ka 3-Bromo-2-chloro-5-(trifluoromethyl)pyridine e nāʻano likeʻole. ʻO ke ala maʻamau ka hoʻokomo ʻana i nā ʻātoma bromine a me ka chlorine i ka hopena e ka bromination a me ka chlorination, e hoʻomaka me ka pyridine. A laila, hoʻokomo ʻia kahi hui trifluoromethyl i kahi hopena trifluoromethylation. Hana ʻia kēia synthesis ma lalo o kahi lewa inert e hōʻoia i ka koho kiʻekiʻe a me ka hopena o ka hopena.
ʻO ka 3-Bromo-2-chloro-5-(trifluoromethyl)pyridine ka palena o ka ʻike palekana. He mea hoʻonāukiuki paha i ka maka, ka hanu a me ka ʻili. I ka wā o ka hoʻohana ʻana, pono e mālama ʻia e pale i ka hoʻopili pololei ʻana me ka ʻili a me nā maka. I ka manawa like, pono e lawe ʻia nā hana pale kūpono i ka wā o ka hana, e like me ke komo ʻana i nā aniani pale, nā mīkina lima a me nā lole pale.
Eia kekahi, i ka wā o ka mālama ʻana a me ka mālama ʻana, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā mea puhi ahi a mālama i ka ventila maikaʻi. I ka wā e hoʻolei ai i ka ʻōpala, pono e hahai ʻia nā lula kūloko a pono e hoʻohana ʻia nā ʻano hoʻolei ʻōpala kūpono. Hoʻohana maikaʻi ʻia a mālama ʻia ma lalo o ke alakaʻi ʻana o nā chemists akamai.
