Amakhodi Engozi	R34 – Ibangela ukusha R51/53 – Ukuba nobuthi ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini. R43 - Ingabangela ukuzwela ngokuthinta isikhumba I-R22 – Iyingozi uma igwinywe
Incazelo Yokuphepha	S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) I-S61 - Gwema ukudedelwa endaweni. Bheka imiyalelo ekhethekile / amaphepha edatha okuphepha. I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu.

4 6-Dichloro-2-methylpyrimidine (CAS# 1780-26-3) isingeniso

I-2-Methyl-4,6-dichloropyrimidine, eyaziwa nangokuthi i-2,4,6-trichloropyrimidine noma i-DCM, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisethulo sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha kwenhlanganisela:

Ikhwalithi:
- Ukubukeka: I-2-methyl-4,6-dichloropyrimidine i-crystal emhlophe noma i-crystalline powder engenambala.
- Ukunyibilika: Inokuncibilika okuphansi emanzini kodwa ukuncibilika okungcono kuzincibilikisi zemvelo.
- Izakhiwo zamakhemikhali: Kuyinhlanganisela ezinzile engajwayele ukubola noma ukusabela ngaphansi kwezimo ezivamile zokusabela kwamakhemikhali.

Sebenzisa:
- I-Solvent: I-2-Methyl-4,6-dichloropyrimidine iyi-solvent ye-organic evame ukusetshenziswa evame ukusetshenziswa kuma-laboratories amakhemikhali ukuze kuncibilike ama-organic compounds, ikakhulukazi lawo angancibiliki emanzini.

Indlela:
- I-2-Methyl-4,6-dichloropyrimidine ingatholakala ngokusabela kwe-2-methylpyrimidine ngegesi ye-chlorine. Lokhu kusabela kudinga ukwenziwa ngaphansi kwezimo ezanele zokungenisa umoya.

Ulwazi Lokuphepha:
- I-2-Methyl-4,6-dichloropyrimidine iyinhlanganisela yemvelo enobuthi obuthile. Iyacasula futhi igqwalise amehlo, isikhumba, kanye nomgudu wokuphefumula. Amagilavu, izibuko, nemishini yokuvikela ukuphefumula kufanele kugqokwe ngesikhathi sokusetshenziswa ukuze kuqinisekiswe ukungena komoya owanele. Esimeni sokungena ngephutha noma ukuhogela, funa usizo lwezokwelapha ngokushesha.
- I-2-Methyl-4,6-dichloropyrimidine idala izingozi zemvelo futhi inobuthi ezintweni eziphila emanzini nasemhlabathini. Lapho usebenzisa futhi ulahla imfucuza, isimiso sokuvikelwa kwemvelo kufanele silandelwe, futhi imfucuza kufanele ilahlwe ngendlela efanele.

Okwedlule: I-Fmoc-D-2-Aminobutyric acid (CAS# 170642-27-0)

Olandelayo: 3 5-Dibromo-4-(trifluoromethyl)aniline (CAS# 1806274-43-0)
