Functional Group

Aryl nitriles are common structural motifs in the synthesis of pharmaceuticals, agrochemicals, and functional materials. The nitrile group can either be retained as a stable functional group in the target molecule or further converted into amides, carboxylic acids, amines, ketones, and ...

In peptide synthesis, impurities do not always originate from “incomplete coupling” or “incomplete deprotection.” Many quality issues arise because certain functional groups enter undesired reaction pathways under specific conditions. Carboxyl and hydroxyl groups are two typical ...

Polyester resins used in coatings are not a single, uniform category. Different polyester resins vary in resin structure, reactive functional groups, curing-agent type, application method, and final coating-film structure.

Teoc [2-(trimethylsilyl)ethoxycarbonyl] is one of the commonly used silyl carbamate protecting groups for amines. Its distinctive feature is that it can be removed under fluoride-triggered conditions, and it is therefore often used in multistep synthesis as an alternative to the more common ...

The nitrile group is a common functional group in medicinal chemistry, agrochemical chemistry, fine chemicals, and functional molecules, and it is also a highly useful synthetic intermediate. It can exist directly as a structural unit within a molecule, and it can also be readily transformed ...
