Chemical Structure

3-(1H-Imidazol-1-yl)acrylaldehyde CAS 21431-75-4 chemical structure

Description

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.

3-(1H-Imidazol-1-yl)acrylaldehyde (CAS 21431-75-4), molecular formula C6H6N2O and molecular weight 122.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(1H-Imidazol-1-yl)acrylaldehyde (C6H6N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 3-(1H-Imidazol-1-yl)acrylaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
