Product Overview
Isobutyl Methyl Ketone (4-Methyl-2-pentanone) is a high-purity solvent meeting ARS and ACS reagent grade specifications, ensuring consistent performance in critical laboratory applications. This colorless liquid features a characteristic ketone odor and boasts a 99%+ assay purity, making it suitable for demanding analytical procedures. With a boiling point of 116°C and low water solubility (1.9 g/L at 20°C), it serves as an effective extraction solvent for organic compounds while maintaining stability under standard lab conditions. The product’s low viscosity (0.58 cP at 20°C) facilitates easy handling in chromatographic applications, while its moderate evaporation rate (relative to butyl acetate = 1) allows for controlled solvent removal. Packaged in amber glass bottles to prevent photodegradation, this reagent maintains its integrity during storage and transport. The dual ARS/ACS certification guarantees compliance with both Indian and international purity standards, eliminating batch-to-batch variability that could compromise experimental results. Its balanced polarity (dielectric constant of 13.11) enables selective solubility for a wide range of organic molecules without reacting with most common laboratory materials.
FAQs
1. What is the difference between ARS and ACS grades in this product?
The ARS grade follows Indian Analytical Reagent Standards while ACS meets American Chemical Society specifications. Both ensure high purity, but ACS typically has stricter heavy metal limits. This product meets both standards simultaneously.
2. Can this solvent be used with plastic labware?
Isobutyl methyl ketone may dissolve certain plastics like polystyrene. Use with PTFE, glass, or HDPE containers. Always check compatibility with your specific plastic type before use.
3. What is the typical shelf life of unopened bottles?
When stored in original packaging at room temperature away from direct sunlight, unopened bottles maintain specifications for 24 months from manufacture date.
4. How does this compare to regular methyl isobutyl ketone?
This ARS/ACS grade product has tighter purity controls (99%+ assay) and lower impurity limits compared to technical grade MIBK. It’s specifically purified to remove peroxides and heavy metals.
5. What safety precautions should be taken during handling?
Use in a fume hood with proper ventilation. Wear nitrile gloves and safety goggles. Avoid inhalation of vapors and skin contact. Keep away from ignition sources as it’s flammable.
