Chemical Structure
Description
As a certified reference material (CRM), (2-(2-Isonicotinoylhydrazinyl)-2-oxoethyl)phosphonic acid 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-(2-Isonicotinoylhydrazinyl)-2-oxoethyl)phosphonic acid (CAS 69152-47-2), a certified reference material (molecular formula C8H10N3O5P, MW 259.16 g/mol) for analytical method development and quality control.
Structurally, (2-(2-Isonicotinoylhydrazinyl)-2-oxoethyl)phosphonic acid (C8H10N3O5P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 259.16 g/mol, it falls into the medium-molecular-weight range. 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.
