Description
As a certified reference material (CRM), 2-Chloro-4-nitro-N-(pyridin-3-ylmethyl)aniline 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.
CATO supplies 2-Chloro-4-nitro-N-(pyridin-3-ylmethyl)aniline (CAS 923729-71-9), a certified reference material (molecular formula C12H10ClN3O2, MW 263.68 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H10ClN3O2, 2-Chloro-4-nitro-N-(pyridin-3-ylmethyl)aniline contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
