| Likhoutu tsa Kotsi | R25 – E chefo ha e koetsoe R36/37/38 – Ho tena mahlo, tsamaiso ya ho hema le letlalo. |
| Tlhaloso ea Tšireletseho | S7/9 - S22 - U se ke ua hema lerole. S24/25 - Qoba ho kopana le letlalo le mahlo. S26 - Ha u kopana le mahlo, hlatsoa hang-hang ka metsi a mangata 'me u batle keletso ea bongaka. S36/37 - Apara liaparo tse loketseng tsa tšireletso le liatlana. S38 - Haeba moea o sa lekana, apara lisebelisoa tse loketseng tsa ho hema. S45 – Ha ho ka etsahala kotsi kapa ha o ikutlwa o sa phele hantle, batla keletso ya bongaka hanghang (bontsha leibole neng kapa neng ha ho kgoneha.)

Motsoako ona o na le ts'ebeliso ea bohlokoa ho motsoako oa lithethefatsi le motsoako oa chefo e bolaeang likokoanyana. E ka sebelisoa e le sebaka sa mahareng bakeng sa ho kopanya metsoako ea bioloji. Ka mohlala, e ka sebelisoa ho kopanya lithethefatsi tse thibelang likokoana-hloko le chefo e bolaeang likokoanyana, joalo-joalo.
The 3-Bromo-2-chloro-5-(trifluoromethyl)pyridine e ka lokisoa ka mekhoa e fapaneng. Mokhoa o tloaelehileng ke ho hlahisa liathomo tsa bromine le chlorine karabelong ka bromination le chlorination, ka ho latellana, ho qala ka pyridine. Ebe, sehlopha sa trifluoromethyl se hlahisoa ka karabelo ea trifluoromethylation. Kakaretso ena e atisa ho etsoa tlas'a sepakapaka sa inert ho netefatsa khetho e phahameng le lihlahisoa tsa karabelo.
The 3-Bromo-2-chloro-5-(trifluoromethyl)pyridine e na le boitsebiso bo fokolang ba tšireletso. E ka 'na ea halefisa mahlo, tsamaiso ea ho hema le letlalo. Nakong ea tšebeliso, tlhokomelo e lokela ho nkoa ho qoba ho kopana ka ho toba le letlalo le mahlo. Ka nako e ts'oanang, mehato e nepahetseng ea tšireletso e lokela ho nkoa nakong ea ts'ebetso, e kang ho roala likhalase tse sireletsang, liatlana le liaparo tse sireletsang.
Ho phaella moo, nakong ea ho tšoara le ho boloka, tlhokomelo e lokela ho nkoa ho thibela ho kopana le lisebelisoa tse tukang le ho boloka moea o motle. Ha ho lahla litšila, ho lokela ho lateloa melao ea sebaka ka seng ’me ho amoheloe mekhoa e loketseng ea ho lahla litšila. E sebelisoa hamolemo le ho tšoaroa tlas'a tataiso ea litsebi tsa k'hemistri tse nang le phihlelo.
