Product Overview

iso-Propyl Alcohol 99.8% For HPLC & UV Spectroscopy (CAS No. 67-63-0) is 2-propanol, a polar protic organic solvent used as a chromatographic modifier and as a solution medium in optical measurements where its spectral background is compatible with the selected analytical region. Its secondary-alcohol structure combines hydrogen-bonding capacity with greater hydrophobic character than methanol or ethanol, providing a distinct solvent-selectivity profile in liquid chromatography.

The HPLC & UV Spectroscopy grade is intended for mobile-phase preparation, chromatographic sample handling and ultraviolet spectroscopic work requiring controlled solvent background. Isopropanol is an established organic modifier in selected HPLC systems.

Typical Applications

• Organic modifier in selected reversed-phase HPLC mobile phases.
• HPLC sample dissolution, dilution and extraction where isopropanol is method-compatible.
• Chromatographic method development using alcohol-based solvent selectivity.
• Preparation of spectroscopic blanks and sample solutions in compatible UV regions.
• UV absorption measurements requiring isopropanol as the specified solvent.
• HPLC solvent exchange and column-washing procedures where technically appropriate.

Common Synonyms

• Isopropanol
• 2-Propanol
• Propan-2-ol
• Isopropyl alcohol
• sec-Propyl alcohol
• IPA

Storage Conditions

Store tightly closed to minimise evaporation, moisture uptake and introduction of UV-active or non-volatile contamination. Limit prolonged exposure to air because peroxide formation can occur in isopropanol, particularly during extended storage or subsequent concentration of aged solvent.
