Methyl ethyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) bụ ihe mgbaze organic nke toxicity dị ntakịrị, nke a na-ahụ n'ọtụtụ ngwa.A na-eji ya na ngwaahịa ụlọ ọrụ mmepụta ihe na nke azụmahịa dị ka ihe mgbaze maka nrapado, agba, na ndị na-ehicha ihe dị ka ihe mgbaze na-eme ihe.Akụkụ sitere n'okike nke ụfọdụ nri, methyl ethyl ketone nwere ike wepụta ya na gburugburu ebe obibi site na ugwu mgbawa na ọkụ ọhịa. A na-eji ya na-emepụta ntụ ntụ na-enweghị anwụrụ ọkụ na resins sịntetik na-enweghị agba, dị ka ihe mgbaze, na mkpuchi mkpuchi.A na-ejikwa ya dị ka ihe na-esi ísì ụtọ na nri.

A na-eji MEK dị ka ihe mgbaze maka usoro mkpuchi dị iche iche, dịka ọmụmaatụ, vinyl, adhesives, nitrocellulose, na mkpuchi acrylic.A na-eji ya na ndị na-ewepu agba, lacquers, varnishes, spray paints, sealers, glues, magnetik teepu, inks printing, resins, rosins, ihicha ngwọta, na maka polymerization.A na-ahụ ya na ngwaahịa ndị ọzọ na-azụ ahịa, dịka ọmụmaatụ, ụlọ na simenti ntụrụndụ, na ngwaahịa na-ejuputa osisi.A na-eji MEK na-eme ka mmanụ na-ete mmanụ na-eme ka ọ dị mma, nbibi nke ọla, na mmepụta akpụkpọ anụ sịntetik, akwụkwọ mpempe akwụkwọ na foil aluminom, yana dị ka kemịkalụ etiti na ihe na-akpali akpali.Ọ bụ ihe mgbaze mmịpụta na nhazi nke ihe oriri na ihe oriri.A nwekwara ike iji MEK mee ka ngwa ịwa ahụ na eze kwụsịchaa.
Na mgbakwunye na nrụpụta ya, ebe nchekwa gburugburu ebe obibi sitere na MEK gụnyere iyuzucha si na jet na injin combustion dị n'ime, yana ọrụ mmepụta ihe dị ka ikuku gas.A na-ahụ ya n'oke anwụrụ ọkụ sịga.A na-emepụta MEK n'ụzọ ndụ ma chọpụta na ọ bụ ngwaahịa nke microbial metabolism.A hụkwara ya na osisi, pheromones ụmụ ahụhụ, na anụ ahụ anụmanụ, na MEK nwere ike bụrụ obere ngwaahịa nke metabolism mammalian nkịtị.Ọ kwụsiri ike n'okpuru ọnọdụ nkịtị mana ọ nwere ike mepụta peroxides na nchekwa ogologo oge;ndị a nwere ike ịbụ ihe mgbawa.
