Acetonitrile ≥99.9%, CHROMASOLV™ Plus for HPLC, Riedel-de Haën™
Acetonitrile

Acetonitrile is a medium-polarity solvent that is miscible with water and a range of organic solvents, but not saturated hydrocarbons. CHROMASOLV® Plus Acetonitrile is suitable for multiple applications including: Mass spectrometry, HPLC, TLC, GPC, UV, GC, Pesticide Residue Analysis, and RNA/DNA Synthesis and Purification.


  • For HPLC, spectrophotometry, and environmental analysis
  • Tested for HPLC-suitability via gradient analysis and UV-VIS spectroscopy
  • Low UV impurity profile
  • Low impurity gradient LC baseline
  • Very low levels of non-volatile impurities
