For similar reasons, it is a popular solvent in cyclic voltammetry. Its ultraviolet transparency UV cutoff, low viscosity and low chemical reactivity make it a popular choice for high-performance liquid chromatography (HPLC). Acetonitrile plays a significant role as the dominant solvent used in oligonucleotide synthesis from nucleoside ...
A UV-Vis spectrophotometer is an analytical instrument that measures the amount of ultraviolet (UV) and visible light that is absorbed by a sample. It is a widely used technique in chemistry, biochemistry, and other fields, to identify and quantify compounds in a variety of samples.
Aniline is a benzenoid compound. The NH 2 group attached to the benzene ring means that there is a lone pair of electrons that can enter into conjugation with the benzene ring resulting in delocalization in the aniline.
As a solvent, hexafluoro-2-propanol is polar and exhibits strong hydrogen bonding properties. Testament to the strength of its hydrogen-bonding tendency is the fact that its 1:1 complex with THF distills near 100 °C. It has a relatively high dielectric constant of 16.7.
To derive SUVA, first, UVC light (UV spectrum subtypes) at 254 nm or 280 nm, [2] is measured in units of absorbance per meter of path length, often the sample must be diluted with ultrapure water because absorbance can be high. [3]
