i-hexahydro-1H-azepine-1-ethanol(CAS#20603-00-3)
| Izimpawu Eziyingozi | C – Iyabola |
| Amakhodi Engozi | R34 – Ibangela ukusha R21/22 – Kuyingozi ukuthinta isikhumba futhi uma ugwinyiwe. |
| Incazelo Yokuphepha | S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. |
| I-Hazard Class | 8 |

Isingeniso
N-(2-hydroxyethyl)hexamethylenediamine. Kuyikristalu eqinile engenambala nokuncibilika okuphezulu nokuzinza. Okulandelayo yisingeniso semvelo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha lwe-HEPES:
【Izakhiwo】
I-HEPES iyisigcina se-alkali ebuthakathaka enobubanzi obuyi-pH 6.8-8.2. Incibilika kahle emanzini futhi ayithinteki kalula ngama-enzyme nama-asidi akhiqizwe amaseli.
【Izinhlelo zokusebenza】
I-HEPES isetshenziswa kabanzi emkhakheni we-biochemistry kanye ne-molecular biology. Isetshenziswa kakhulu njengesivimbeli se-physiological semidiya yesiko lamaseli kanye nesivimbeli sokusabela okukhangayo kwama-enzyme namaprotheni. I-HEPES ingaphinda isetshenziselwe ukuhlukaniswa kwe-electrophoresis ye-DNA ne-RNA, ukungcoliswa kwe-fluorescent, ukuhlaziya umsebenzi we-enzyme kanye neminye imisebenzi yokuhlola.
【Indlela】
I-HEPES ingahlanganiswa ngokusabela kwe-6-chlorohexamethylenetriamine nge-2-hydroxyacetic acid. Inqubo ethize yokulungiselela imi kanje:
1. Chaza i-6-chlorohexamethylenetriamine kusisombululo se-sodium hydroxide ukuze ukhiqize usawoti we-sodium we-triamine.
2. I-2-Hydroxyacetic acid yengezwa ukwenza i-N-(2-hydroxyethyl)hexamethylenediamine.
3. Umkhiqizo ucwebezelwe futhi uhlanzwe ukuze uthole ama-HEPES amsulwa.
【Ulwazi Lokuphepha】
1. Gwema ukuthintana ngqo namehlo nesikhumba, hlambulula ngokushesha ngamanzi amaningi uma uthintwe ungaqondile.
2. Lapho usebenzisa futhi ulondoloza, gwema ukuthintana nama-oxidants, izinto eziphilayo nama-asidi aqinile ukuze uvimbele ukusabela okuyingozi.
3. Lapho usebenza, naka ukuzivikela komuntu siqu, gqoka izibuko zokuphepha, amagilavu okuzivikela kanye nezingubo zaselabhorethri. Sebenza endaweni yaselabhorethri enomoya omuhle.
4. Akuvunyelwe ngokuphelele ukudla, ukuhogela umoya noma ukwethula ohlelweni lokugaya ukudla. Sicela ugcine ukuhlanzeka okuhle kwelabhorethri ngesikhathi sokusetshenziswa.
