Product Overview
4-Methyl-2-pentanone (99.5% spectrophotometric grade) is a high-purity solvent engineered for applications demanding exceptional optical clarity and minimal impurity interference. Its refined distillation process eliminates UV-absorbing contaminants, making it ideal for spectrophotometric analyses where baseline stability is critical. The solvent’s balanced evaporation rate ensures consistent sample preparation without residual artifacts, while its low water content (<0.05%) prevents spectral distortions in moisture-sensitive protocols. Compatible with most organic compounds, it serves as a versatile extraction medium and HPLC mobile phase component. The spectrophotometric grade certification guarantees lot-to-lot consistency, with strict quality controls verifying absorbance values below 0.05 AU at 250nm (1cm path). Packaged in amber glass bottles to prevent photodegradation, this solvent maintains its integrity during storage and handling. Its mild odor and moderate flash point (15°C) allow for safe use in standard lab environments when proper ventilation is observed.
FAQs
1. What is the maximum absorbance cutoff for this 4-Methyl-2-pentanone grade?
This spectrophotometric grade maintains absorbance below 0.05 AU at 250nm (1cm path length), ensuring minimal interference in UV/Vis applications.
2. Can this solvent be used with plastic labware?
It may dissolve certain plastics like polystyrene; use glass or PTFE containers for long-term storage or reactions.
3. How does this compare to technical-grade 4-Methyl-2-pentanone?
Spectrophotometric grade undergoes additional purification to remove UV-absorbing impurities absent in technical grades, which may contain up to 2% contaminants.
4. What’s the typical shelf life under proper storage?
Unopened bottles retain full specifications for 24 months when stored at 15-25°C away from direct light and moisture.
5. Is this solvent compatible with aqueous solutions?
It has limited water solubility (~2% v/v) but can form stable emulsions with surfactants for specific extraction protocols.
