Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 195.15 g/mol gives 4-cyano-3-fluoro-5-methoxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-cyano-3-fluoro-5-methoxybenzoic acid (CAS 1805456-35-2), a certified reference material (molecular formula C9H6FNO3, MW 195.15 g/mol) for analytical method development and quality control.
The molecular framework of 4-cyano-3-fluoro-5-methoxybenzoic acid (C9H6FNO3) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
