Deuterated chloroform cdcl3

Manufactured by Avantor
Visit Supplier
Sourced in Spain

Deuterated chloroform (CDCl3) is a commonly used solvent in nuclear magnetic resonance (NMR) spectroscopy. It is a clear, colorless liquid with a distinct, sweet odor. Deuterated chloroform is a stable isotope of chloroform, where the hydrogen atoms have been replaced with deuterium atoms. This substitution makes it particularly useful for NMR analysis, as the deuterium atoms provide a distinct signal that does not interfere with the signals from the compounds being analyzed.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
