1-Hydroxyethyl-3-methylimidazolium chloride CAS 61755-34-8

Product Name: 1-Hydroxyethyl-3-methylimidazolium chloride

CAS Number: 61755-34-8

Description

1-Hydroxyethyl-3-methylimidazolium chloride is a functionalized ionic liquid (IL). It features an imidazolium cation with a methyl group and a hydroxyethyl group, paired with a chloride anion. The presence of the hydroxyl group (OH) on the cation imparts specific functionalities and often increases its hygroscopicity and ability to form hydrogen bonds. This compound is typically a salt that can be liquid at or near room temperature, or a low-melting solid, depending on its purity and water content. It is recognized for its utility in biomass processing and as a versatile chemical intermediate.
