Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 138.12 g/mol gives (E)-3-(1H-imidazol-2-yl)acrylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(E)-3-(1H-imidazol-2-yl)acrylic acid (CAS 155170-45-9) is a high-purity analytical reference standard with the molecular formula C6H6N2O2 and a molecular weight of 138.12 g/mol.
The molecular framework of (E)-3-(1H-imidazol-2-yl)acrylic acid (C6H6N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures (E)-3-(1H-imidazol-2-yl)acrylic acid 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.
