Descripción

Descripción general

Acetonitrile (MeCN) is widely employed as a solvent in various studies and has high dielectric constant (37.5). Various purification procedures to obtain different grades of acetonitrile for use in different studies (polarography, spectroscopy, etc.) have been reported by many researchers.

Aplicación

Acetonitrile has been used to compose the gradient system for the HPLC detection of diphenylmethane diisocyanate, a polymeric degradation product.

New Quality UPLC Plus Acetonitrile is suitable for all applications including:
Mass spectrometry, HPLC, TLC, GPC, UV, IR, GC, Pesticide Residue Analysis, and RNA/DNA Synthesis and Purification.
