Methyl isobutyl ketone (MIBK) is an organic solvent. MIBK is among the top ten most popular organic solvents used in industry. MIBK is occasionally found as a volatile component of urine. MIBK in urine is considered as a biological marker of occupational exposure to this solvent. Olfactory perception is significant but adaptation may occur. The typical toxicity effects of MIBK in humans exposed at 50 to 100 ppm are mucous membrane irritation and weak effects on the central nervous system (CNS) such as headache. Visual dysfunction has been reported in workers exposed to a mixture of organic solvents containing MIBK. Memory impairment was detected in clinical observation on a 44-year-old man who had been exposed to MIBK at 100 ppm for more than 10 years. Regarding to the route of absorption, skin penetration of MIBK is substantial.

These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol.KetonesOrganic compoundsOrganic oxygen compoundsOrganooxygen compoundsCarbonyl compoundsAliphatic acyclic compoundsHydrocarbon derivativesOrganic oxidesAliphatic acyclic compoundHydrocarbon derivativeKetoneOrganic oxideOxygenated hydrocarbonsketoneLiquidlogp1.31logs-0.96solubility1.10e+01 g/lmelting_point-84 oClogp1.54pka_strongest_acidic19.61pka_strongest_basic-7.3iupac4-methylpentan-2-oneaverage_mass100.1589mono_mass100.088815006smilesCC(C)CC(C)=OformulaC6H12OinchiInChI=1S/C6H12O/c1-5(2)4-6(3)7/h5H,4H2,1-3H3inchikeyNTIZESTWPVYFNL-UHFFFAOYSA-Npolar_surface_area17.07refractivity29.97polarizability12.05rotatable_bond_count2acceptor_count1donor_count0physiological_charge0formal_charge0Specdb::NmrTwoD1853Specdb::MsIr1850Specdb::MsIr1851Specdb::CMs12978Specdb::CMs26808Specdb::CMs27135Specdb::CMs27795Specdb::CMs28322Specdb::CMs99787Specdb::CMs99788Specdb::CMs99789Specdb::CMs99790Specdb::CMs169925Specdb::NmrOneD1918Specdb::NmrOneD129138Specdb::NmrOneD129139Specdb::NmrOneD129140Specdb::NmrOneD129141Specdb::NmrOneD129142Specdb::NmrOneD129143Specdb::NmrOneD129144Specdb::NmrOneD129145Specdb::NmrOneD129146Specdb::NmrOneD129147Specdb::NmrOneD129148Specdb::NmrOneD129149Specdb::NmrOneD129150Specdb::NmrOneD129151Specdb::NmrOneD129152Specdb::NmrOneD129153Specdb::NmrOneD129154Specdb::NmrOneD129155Specdb::NmrOneD129156Specdb::NmrOneD129157Specdb::MsMs2173Specdb::MsMs2174Specdb::MsMs2175Specdb::MsMs5807Specdb::MsMs5808Specdb::MsMs5809Specdb::MsMs5810Specdb::MsMs11966Specdb::MsMs11967Specdb::MsMs11968Specdb::MsMs18638Specdb::MsMs18639Specdb::MsMs18640Specdb::MsMs2412067Specdb::MsMs2412068Specdb::MsMs2412069Specdb::MsMs2550887Specdb::MsMs2550888Specdb::MsMs2550889HMDB02939#<Reference:0x0000555675db8ff0>#<Reference:0x0000555675db8e38>#<Reference:0x0000555675db8c80>#<Reference:0x0000555675db8ac8>#<Reference:0x0000555675db8910>AnatidaeType 1specificAnatidae8830BeefaloType 1specificBos taurus X Bison bison297284BeerType 2specific0.120.120.12mg/100 gBisonType 1specificBison bison9901Black elderberryType 1specificSambucus nigra4202BlackberryType 1specificRubusBuffaloType 1specificBubalus bubalis89462Cattle (Beef, Veal)Type 1specificBos taurus9913ChickenType 1specificGallus gallus9031CitrusUnknowngenericColumbidae (Dove, Pigeon)Type 1specificColumbidae8930DeerType 1specificCervidae9850Domestic goatType 1specificCapra aegagrus hircus9925Domestic pigType 1specificSus scrofa domestica9825ElkType 1specificCervus canadensis1574408EmuType 1specificDromaius novaehollandiae8790European rabbitType 1specificOryctolagus9984Evergreen blackberryType 1specificRubus laciniatusFruitsUnknowngenericGingerType 1specificZingiber officinale94328Greylag gooseType 1specificAnser anser8843Guinea henType 1specificNumida meleagris8996HorseType 1specificEquus caballus9796Mallard duckType 1specificAnas platyrhynchos8839Mountain hareType 1specificLepus timidus62621Mule deerType 1specificOdocoileus9871NutsUnknowngenericOstrichType 1specificStruthio camelus8801PheasantType 1specificPhasianus colchicus9054QuailType 1specificPhasianidae9005RabbitType 1specificLeporidae9979Rock ptarmiganType 1specificLagopus muta64668Sheep (Mutton, Lamb)Type 1specificOvis aries9940SquabType 1specificColumba8931Sweet cherryType 1specificPrunus avium42229TurkeyType 1specificMeleagris gallopavo9103Velvet duckType 1specificMelanitta fusca371864Wild boarType 1specificSus scrofa9823dairyfruitygreenherbalsharpsolventspiceflavor936A substance, extract, or preparation for diffusing or imparting an agreeable or attractive smell.perfumery1206A substance, extract, or preparation for diffusing or imparting an agreeable or attractive smell.
