Product Name – Dichloromethane, 99.8%, for spectroscopy, stabilized with amylene Quantity/Pack Size – 2.5LT, 500ML Form – Liquid Grade – Spectroscopy Application – Solvent for UV/IR spectroscopy, chromatography
Product Overview
This high-purity dichloromethane (DCM) at 99.8% concentration is specifically formulated for spectroscopy applications, stabilized with amylene to prevent decomposition. The solvent exhibits exceptional transparency in the UV-visible range, making it ideal for analytical techniques requiring minimal interference. Its low boiling point (39.6°C) and rapid evaporation rate ensure efficient sample preparation without residue. The spectroscopy-grade purity guarantees minimal impurities, with water content maintained below 0.01% to prevent spectral distortions. The amylene stabilization extends shelf life while maintaining consistent performance across repeated analyses. This DCM variant demonstrates excellent solvency for organic compounds while remaining compatible with most laboratory glassware and plasticware. The product meets stringent quality standards for chromatographic applications, offering consistent retention times and peak shapes. Its controlled acidity and peroxide levels make it suitable for sensitive detection methods. The solvent’s refractive index (1.4242) and density (1.325 g/mL) remain stable across storage conditions, ensuring reproducible results in quantitative analyses.
FAQs
1. What makes this dichloromethane suitable for spectroscopy?
The 99.8% purity level with amylene stabilization ensures minimal UV absorbance below 240nm, while the controlled impurity profile prevents spectral interference in both UV-Vis and IR applications.
2. How does amylene stabilization affect the solvent’s performance?
Amylene acts as a radical scavenger, preventing the formation of phosgene and hydrochloric acid during storage, which maintains the solvent’s transparency and extends its usable shelf life without compromising analytical results.
3. Can this DCM be used for HPLC applications?
While primarily designed for spectroscopy, its high purity and low UV cutoff make it compatible with normal-phase HPLC systems, though gradient compatibility should be verified with your specific column chemistry.
4. What storage conditions are recommended to maintain quality?
Store tightly sealed in the original amber glass bottle at 15-25°C, away from direct sunlight and ignition sources, with headspace minimized to reduce oxidative degradation.
5. How does this compare to unstabilized dichloromethane?
The amylene-stabilized version offers significantly longer shelf stability (12+ months unopened) and reduced risk of acidic byproduct formation compared to unstabilized DCM, which may degrade within 3-6 months.
