Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 169.10 g/mol gives 2,5-Dinitropyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,5-Dinitropyridine (CAS 15009-92-4) is a high-purity analytical reference standard with the molecular formula C5H3N3O4 and a molecular weight of 169.10 g/mol.
Structurally, 2,5-Dinitropyridine (C5H3N3O4) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 169.10 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 2,5-Dinitropyridine 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.
