Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izimpawu Eziyingozi Xi - Irritant
Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
I-R33 – Ingozi yemiphumela eqoqwayo
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36 – Gqoka izingubo ezifanele zokuzivikela.
I-S24/25 - Gwema ukuthintana nesikhumba namehlo.

Isingeniso

Ngokuvamile isetshenziswa njenge-reagent ngesikhathi se-esterification ye-2,2,6,6-tetramethyl-4-oxopiperidinyl-1-oxyl ukuze ikhiqize i-4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl 4-formylbenzoate.
