Yes, it is flammable and its vapours can cause irritation to the eyes, skin, and respiratory system. It must be handled with appropriate personal protective equipment (PPE) and in well-ventilated areas.
MIBK is the standard abbreviation for Methyl Isobutyl Ketone, used widely in technical and industrial documents for brevity.
MIBK has limited solubility in water (approximately 2% at 20°C). It is considered a moderately polar, water-immiscible solvent, which is why it's useful for liquid-liquid extractions.
Depending on the application, solvents like methyl ethyl ketone (MEK), acetone, or certain acetates might be considered, though they have different evaporation rates and solvency powers.
