Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 423.03 g/mol gives Ethyl 5,6-dichloro-2-(3-iodophenyl)pyrimidine-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 5,6-dichloro-2-(3-iodophenyl)pyrimidine-4-carboxylate (CAS 1956380-69-0) is a high-purity analytical reference standard with the molecular formula C13H9Cl2IN2O2 and a molecular weight of 423.03 g/mol.
The molecular framework of Ethyl 5,6-dichloro-2-(3-iodophenyl)pyrimidine-4-carboxylate (C13H9Cl2IN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Ethyl 5,6-dichloro-2-(3-iodophenyl)pyrimidine-4-carboxylate 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.
