Chemical Structure
Description
The molecular framework of Methyl 2-fluoro-5-[3-(methoxycarbonyl)-5-nitrophenyl]benzoate (C16H12FNO6) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Methyl 2-fluoro-5-[3-(methoxycarbonyl)-5-nitrophenyl]benzoate (CAS 1820620-22-1) is a high-purity analytical reference standard with the molecular formula C16H12FNO6 and a molecular weight of 333.27 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Methyl 2-fluoro-5-[3-(methoxycarbonyl)-5-nitrophenyl]benzoate 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.
