2-(3-pyridinylmethylideneamino)phenol 2-(pyridin-3-ylmethylideneamino)phenol 51422-01-6 A828587 (CAS 51422-01-6), molecular formula C4H2ClFN2 and molecular weight 132.52 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(3-pyridinylmethylideneamino)phenol 2-(pyridin-3-ylmethylideneamino)phenol 51422-01-6 A828587 (C4H2ClFN2) is characterized by a nitrile group, fluorine/chlorine substitution. 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.

As a certified reference material (CRM), 2-(3-pyridinylmethylideneamino)phenol 2-(pyridin-3-ylmethylideneamino)phenol 51422-01-6 A828587 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.
