3-(Benzyloxy)-1-bromo-2,4-difluoro-5-methylbenzene CAS 1881332-68-8

Description

Compared with other compounds in its class, the molecular weight of 313.14 g/mol gives 3-(Benzyloxy)-1-bromo-2,4-difluoro-5-methylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(Benzyloxy)-1-bromo-2,4-difluoro-5-methylbenzene (CAS 1881332-68-8) is a high-purity analytical reference standard with the molecular formula C14H11BrF2O and a molecular weight of 313.14 g/mol.

Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system, 3-(Benzyloxy)-1-bromo-2,4-difluoro-5-methylbenzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
