Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 198.19 g/mol gives Ethyl 4-fluoro-3-methoxybenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 4-fluoro-3-methoxybenzoate (CAS 773135-05-0) is a high-purity analytical reference standard with the molecular formula C10H11FO3 and a molecular weight of 198.19 g/mol.
The molecular framework of Ethyl 4-fluoro-3-methoxybenzoate (C10H11FO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Ethyl 4-fluoro-3-methoxybenzoate 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.
