Dichloromethane HPLC 2.5L
Dichloromethane (DCM) HPLC Grade in a 2.5L volume is a highly purified, rapidly evaporating solvent used primarily as a mobile phase component in High-Performance Liquid Chromatography (HPLC) and Liquid Chromatography-Mass Spectrometry (LC-MS). The 2.5L amber glass bottle packaging is the standard lab-scale configuration designed to fit directly into automated HPLC solvent management systems while protecting the chemical from light degradation.
Core Laboratory Applications
HPLC and Liquid Chromatography Mobile Phase: It acts as an elite solvent carrier for both analytical and preparative separations.
It is widely used in normal-phase chromatography and gel permeation chromatography (GPC).
Spectroscopy & Environmental Testing: Because it has extremely low UV absorption (high UV-permeability) in the far UV region (230190 nm), it ensures crisp, high-resolution results with low baseline noise during UV-Vis or fluorescence detection.Solid-Phase Extraction (SPE) &
Compound Isolation: It is used as a powerful extraction solvent in pharmaceutical and environmental testing labs to isolate organic pollutants, synthetic compounds, or active pharmaceutical ingredients from matrices.
Food and Beverage Analysis: Used specifically for extracting flavourings, testing hop extracts, and quantifying caffeine or other residues due to its highly volatile and inert properties.
Unique Properties of HPLC Grade 2.5L Bottles
High Purity and Ultra-low Residue: It boasts a chemical assay of \(\geq 99.8\%\) or \(99.99\%\) purity. It is pre-filtered down to 0.2 \(\mu \)m to protect delicate column packing from particulate blocking.
Chemical Stabilization: The solvent is commonly stabilized with roughly 30 ppm of amylene to prevent degradation or the formation of phosgene over time.
Dichloromethane (Methylene chloride) may be used in the following processes:
As an extractant for 2,2-dithioethyl-4-(2-pyridyl)-4-butyro--lactone.

Dichloromethane may also be used in ultrasonic baths for cleaning and protection of aluminum coating over atactic-PMMA (poly(methyl methacrylate)) for dielectric studies
