Description

Compared with other compounds in its class, the molecular weight of 390.17 g/mol gives Diethyl 2-(((5-iodopyridin-2-yl)amino)methylene)malonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Diethyl 2-(((5-iodopyridin-2-yl)amino)methylene)malonate (CAS 865658-80-6), molecular formula C13H15IN2O4 and molecular weight 390.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution, Diethyl 2-(((5-iodopyridin-2-yl)amino)methylene)malonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Diethyl 2-(((5-iodopyridin-2-yl)amino)methylene)malonate 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.
