Chemical Structure
Description
2,3-Diamino-6-chloropyridine 6-Chloro-2,3-diaminopyridine 40851-95-4 (CAS 40851-95-4) is a high-purity analytical reference standard with the molecular formula C5H6ClN3 and a molecular weight of 143.57 g/mol.
The molecular framework of 2,3-Diamino-6-chloropyridine 6-Chloro-2,3-diaminopyridine 40851-95-4 (C5H6ClN3) is characterized by a nitrile group, 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-Diamino-6-chloropyridine 6-Chloro-2,3-diaminopyridine 40851-95-4 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.
