What is CAS No 108-10-1 MIBK?

CAS No 108-10-1 MIBK is the organic chemical methyl isobutyl ketone, also known as 4-methyl-2-pentanone. Methyl isobutyl ketone (MIBK) is a ketone that is widely used as a solvent. Unlike the other common ketone solvents, acetone and MEK, MIBK has quite low solubility in water, allowing it to be used for liquid-liquid extraction. CAS No 108-10-1 MIBK has a similar polarity to the ester solvent ethyl acetate, but higher stability towards aqueous acid or base than ethyl acetate.
