Metabolite Identification
Common NameMethyl isobutyl ketone
DescriptionMethyl 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. (PMID: 12592578 , 17485256 , 16464817 , 5556886 ).

Chemical Taxonomy
Description Belongs to the class of organic compounds known as ketones. 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.
