Chemical Structure
Description
2-(3-Benzyl-2-imino-2,3-dihydro-1H-benzo[d]imidazol-1-yl)acetic acid (CAS 40783-87-7) is a high-purity analytical reference standard with the molecular formula C16H15N3O2 and a molecular weight of 281.31 g/mol.
2-(3-Benzyl-2-imino-2,3-dihydro-1H-benzo[d]imidazol-1-yl)acetic acid (C16H15N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 2-(3-Benzyl-2-imino-2,3-dihydro-1H-benzo[d]imidazol-1-yl)acetic acid 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.
