Chemical Structure
Description
As a certified reference material (CRM), Diethyl pyridin-3-ylphosphonate 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.
Diethyl pyridin-3-ylphosphonate (CAS 53340-10-6) is a high-purity analytical reference standard with the molecular formula C9H14NO3P and a molecular weight of 215.19 g/mol.
Based on its molecular formula C9H14NO3P, Diethyl pyridin-3-ylphosphonate contains an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.19 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.
