Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 174.58 g/mol gives 2-Methyl-3-nitropyridine Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Methyl-3-nitropyridine Hydrochloride (CAS 63585-69-3), molecular formula C6H6N2O2HCl and molecular weight 174.58 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Methyl-3-nitropyridine Hydrochloride (C6H6N2O2HCl) is characterized by an amide group, a carboxylic acid 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), 2-Methyl-3-nitropyridine Hydrochloride 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.
