Chemical Structure
Description
CATO manufactures 1-(1H-Imidazol-2-yl)ethan-1-one (hydrochloride) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
1-(1H-Imidazol-2-yl)ethan-1-one (hydrochloride) (CAS 1955506-52-1), molecular formula C5H6N2OHCl and molecular weight 146.57 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(1H-Imidazol-2-yl)ethan-1-one (hydrochloride) is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.57 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
