3-Bromo-2-thiophenecarboxylic acid (CAS# 7311-64-0)
| Izimpawu Eziyingozi | Xi - Irritant |
| Amakhodi Engozi | R43 - Ingabangela ukuzwela ngokuthinta isikhumba R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu. I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. |
| I-WGK Germany | 3 |
| Ikhodi ye-HS | 29349990 |
| I-Hazard Class | I-IRRITANT |
Isingeniso
I-Acid iyinhlanganisela yemvelo enefomula yamakhemikhali ethi C6H4BrO2S.
Imvelo:
-Ukubukeka: i-asidi iqinile emhlophe kuya kokuphuzi.
-I-Solubility: Incibilika ku-chloroform, i-acetone ne-chlorinated methane.
-Indawo yokuncibilika: mayelana ne-116-118 degrees Celsius.
Sebenzisa:
I-asidi okufanele isetshenziswe ivame ukusetshenziswa njengento ebalulekile ekuhlanganiseni kwe-organic synthesis.
-Ingasetshenziselwa ukwakha izinhlanganisela eziphilayo eziqukethe izakhiwo zendandatho ye-thiophene.
Indlela Yokulungiselela: Ziningi izindlela zokwenziwa ze
-i-anacid. Enye yezindlela ezivame ukusetshenziswa ukusebenzisa i-bromoacetic acid njengento eluhlaza, isabela nge-thiophene ngaphansi kwezimo ze-alkaline ukukhiqiza i-3-bromothiophene, bese yenza ukusabela kwe-carboxylic ngaphansi kwezimo ezine-asidi.
Ulwazi Lokuphepha:
-i-asidi ingase icasule amehlo, isikhumba kanye nesistimu yokuphefumula.
-Ngesikhathi sokusetshenziswa, kufanele kuqashelwe ukugwema ukuhogela uthuli noma ukuthintana nesikhumba namehlo.
-Gqoka izinto zokuzivikela ezifanele njengamagilavu elebhu, izibuko nezihlangu zobuso ngaphambi kokuthi usebenze.
-Uma uthinta isikhumba noma amehlo, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha. Izinyathelo zosizo lokuqala ezifanele zizohlinzekwa uma kunesidingo.
