4-Cyano-3-fluorophenyl 4-pentylbenzoate CAS 86786-89-2

Description

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.

4-Cyano-3-fluorophenyl 4-pentylbenzoate (CAS 86786-89-2), molecular formula C19H18FNO2 and molecular weight 311.35 g/mol, is a CATO reference standard with documented purity and traceability.

4-Cyano-3-fluorophenyl 4-pentylbenzoate (C19H18FNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
