Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 311.16 g/mol gives Fenclofenac Methyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Fenclofenac Methyl Ester (CAS 81585-78-6), a certified reference material (molecular formula C15H12Cl2O3, MW 311.16 g/mol) for analytical method development and quality control.
Fenclofenac Methyl Ester (C15H12Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
