Product Overview

Dichloromethane 99.8% For HPLC & UV Spectroscopy (CAS No. 75-09-2) is an instrumental-grade methylene chloride intended for methods requiring controlled ultraviolet background, low non-volatile residue and consistent chromatographic behaviour. Its useful solvating strength and rapid volatility support dissolution, extraction and handling of hydrophobic and moderately polar analytes in compatible normal-phase and non-aqueous liquid-chromatographic systems.

The HPLC & UV Spectroscopy grade is intended for mobile-phase preparation, sample dilution, chromatographic blanks and optical measurements in method-compatible wavelength regions.

Typical Applications

• Mobile-phase component in normal-phase and compatible non-aqueous HPLC methods.
• Preparation and dilution of hydrophobic or moderately polar samples for HPLC.
• Extraction and sample cleanup before liquid-chromatographic analysis.
• Preparation of HPLC mobile-phase, sample and procedural blanks.
• Solvent for UV and visible spectroscopic sample and reference solutions.
• Analytical and preparative liquid chromatography where dichloromethane is compatible with the stationary phase and detector.

Common Synonyms

• Methylene Chloride
• Methylene Dichloride
• Methylene Bichloride
• Methane Dichloride
• Methane, Dichloro-
• DCM
• Dichloromethane

Storage Conditions

Store in a tightly closed container protected from excessive heat, evaporation, moisture and chromatographic contamination. Use clean instrumental-grade dispensing equipment and minimise repeated opening to preserve solvent background, low-residue characteristics and optical cleanliness.
