Chemical Structure

Methyl 4-(benzyloxy)-3,5-difluorobenzoate CAS 1431533-45-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 278.25 g/mol gives Methyl 4-(benzyloxy)-3,5-difluorobenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 4-(benzyloxy)-3,5-difluorobenzoate (CAS 1431533-45-7) is a high-purity analytical reference standard with the molecular formula C15H12F2O3 and a molecular weight of 278.25 g/mol.

The molecular framework of Methyl 4-(benzyloxy)-3,5-difluorobenzoate (C15H12F2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
