Description

Compared with other compounds in its class, the molecular weight of 170.60 g/mol gives 3-oxo-1H,2H,3H-1,4$l^{5}-imidazo[1,2-a][1$l^{5}]pyridin-4-ylium chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-oxo-1H,2H,3H-1,4$l^{5}-imidazo[1,2-a][1$l^{5}]pyridin-4-ylium chloride (CAS 28036-37-5), molecular formula C7H7N2OCl and molecular weight 170.60 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-oxo-1H,2H,3H-1,4$l^{5}-imidazo[1,2-a][1$l^{5}]pyridin-4-ylium chloride (C7H7N2OCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 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).

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), 3-oxo-1H,2H,3H-1,4$l^{5}-imidazo[1,2-a][1$l^{5}]pyridin-4-ylium chloride 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.
