Chemical Structure
Description
CATO supplies Sodium 2,4-dinitrophenolate (wet with ~15% water w/w) (CAS 1011-73-0), a certified reference material (molecular formula C6H3N2O5Na, MW 206.09 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H3N2O5Na, Sodium 2,4-dinitrophenolate (wet with ~15% water w/w) contains a carbohydrate-derived structure, an amide group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 206.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Sodium 2,4-dinitrophenolate (wet with ~15% water w/w) 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.
