Chemical Structure
Description
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-Butyl-3-methyl-1H-imidazol-3-ium (S)-2-hydroxypropanoate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
1-Butyl-3-methyl-1H-imidazol-3-ium (S)-2-hydroxypropanoate (CAS 878132-20-8), molecular formula C8H15N2C3H5O3 and molecular weight 228.29 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
