Description

Compared with other compounds in its class, the molecular weight of 336.36 g/mol gives Methyl 3-[3-(benzyloxy)phenyl]-4-fluorobenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 3-[3-(benzyloxy)phenyl]-4-fluorobenzoate (CAS 1393441-85-4) is a high-purity analytical reference standard with the molecular formula C21H17FO3 and a molecular weight of 336.36 g/mol.

Structurally, Methyl 3-[3-(benzyloxy)phenyl]-4-fluorobenzoate (C21H17FO3) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 336.36 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
