Chemical Structure
Description
The occurrence of Diethyl 5-(3-fluorophenyl)-3-hydroxy-1-methyl-1H-pyrrole-2,4-dicarboxylate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diethyl 5-(3-fluorophenyl)-3-hydroxy-1-methyl-1H-pyrrole-2,4-dicarboxylate (CAS 1263215-38-8), molecular formula C17H18FNO5 and molecular weight 335.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Diethyl 5-(3-fluorophenyl)-3-hydroxy-1-methyl-1H-pyrrole-2,4-dicarboxylate (C17H18FNO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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), Diethyl 5-(3-fluorophenyl)-3-hydroxy-1-methyl-1H-pyrrole-2,4-dicarboxylate 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.
