Chemical Structure
Description
As a certified reference material (CRM), 4-(1H-imidazol-5-yl)benzaldehyde 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.
4-(1H-imidazol-5-yl)benzaldehyde (CAS 149169-88-0), molecular formula C10H8N2O and molecular weight 172.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(1H-imidazol-5-yl)benzaldehyde (C10H8N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
