Izimpawu Eziyingozi C - Ezonakele
Amakhodi Engozi
R34 - Ibangela ukusha
R20/21/22 - Kuyingozi ngokuhogela, ukuthintana nesikhumba futhi uma ukugwinyile.
Incazelo Yokuphepha
S26 - Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S27 - Khumula ngokushesha zonke izingubo ezingcolile.
I-S36/37/39 - Gqoka izingubo zokuzivikela ezifanele, amagilavu nokuvikela iso/ubuso.
S45 - Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)

Ukupakisha Iqembu II
I-2-Butynoic Acid (i-Tetrolic Acid) (i-CAS: 590-93-2) isetshenziswa njengendawo ephakathi kwe-organic synthesis kanye nemithi.Isetshenziswa njenge-synthon ekuphenduleni okuhlukahlukene, okubandakanya i-cylcoalkylation yama-phenols kuya kuma-flavone nama-chromone.Ibandakanyeka ekujikelezeni kwe-gamma-butyrolactones.
I-2-Butynoic Acid inezici ezimbili ze-alkynes ne-carboxylic acid, futhi ingenza ukunciphisa, ukuhlanganisa, i-oxidation, i-esterification kanye ne-cyclization, kanye nokwakhiwa kosawoti kanye ne-acid chloride.
Isetshenziswa ochungechungeni lokusabela ukuze kuhlanganiswe imicu, efana ne-cyclic acylation yama-phenols kuma-cyclic ketones noma ama-chromone, kanye ne-cyclization ye-γ-butyrolactone.
I-2-Butynoic Acid ingasetshenziselwa ukulungiswa kwe-dibromocrotonic acid, i-ethoxycrotonic acid, i-butynic acid ethyl ester, i-butynyl (acid) chloride ne-butynyl (acid) amide.
