Product Overview
Ethyl acetate, 99.5%+ purity, is a premium-grade solvent specifically formulated for spectroscopy applications. This high-purity variant ensures minimal interference in UV, IR, and NMR analyses, delivering reliable and reproducible results. Its low water content and absence of UV-absorbing impurities make it ideal for sensitive spectroscopic techniques where even trace contaminants can distort readings. The solvent’s rapid evaporation rate and excellent solvency power further enhance its utility in sample preparation and chromatographic separations. Manufactured under stringent quality controls, this ethyl acetate meets international spectroscopy-grade standards, guaranteeing consistency across batches. Its stability under standard lab conditions ensures long shelf life without degradation, while its compatibility with common lab materials like glass and PTFE simplifies handling. Whether used as a mobile phase or for sample dilution, this solvent maintains peak performance, reducing the need for repeated calibrations or corrections. The 99.5%+ purity specification is verified through rigorous testing, including GC and UV absorbance analysis, to confirm adherence to spectroscopic requirements. Its neutral odor and low toxicity profile also contribute to a safer lab environment compared to harsher alternatives.
FAQs
1. What is the difference between spectroscopy-grade and reagent-grade ethyl acetate?
Spectroscopy-grade ethyl acetate undergoes additional purification steps to remove UV-absorbing impurities and moisture, which are critical for accurate spectroscopic analysis. Reagent-grade may contain trace contaminants that interfere with light absorption measurements.
2. Can this ethyl acetate be used for HPLC applications?
While primarily designed for spectroscopy, its high purity makes it suitable for some HPLC applications. However, for dedicated HPLC use, a solvent labeled specifically for HPLC is recommended to ensure compatibility with column materials and detectors.
3. How should I store this solvent to maintain its purity?
Store the bottle tightly sealed in a cool, dry place away from direct sunlight and ignition sources. Use within 12 months of opening for optimal performance, and avoid exposure to air to prevent moisture absorption.
4. Is this ethyl acetate compatible with plastic containers?
It can dissolve certain plastics like polystyrene or polyethylene over time. For long-term storage or repeated use, glass or PTFE-lined containers are preferred to prevent contamination or container degradation.
5. What alternatives exist if I need a lower-evaporation-rate solvent for spectroscopy?
For applications requiring slower evaporation, consider isopropyl acetate or butyl acetate, though their UV cutoff and polarity differ. Always verify compatibility with your specific spectroscopic method before substitution.
