2-Bromo-6-ethoxy-4-formylphenyl 4-methoxybenzoate CAS 444066-10-8

Description

The occurrence of 2-Bromo-6-ethoxy-4-formylphenyl 4-methoxybenzoate is closely related to a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Bromo-6-ethoxy-4-formylphenyl 4-methoxybenzoate (CAS 444066-10-8) is a high-purity analytical reference standard with the molecular formula C17H15BrO5 and a molecular weight of 379.20 g/mol.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution, 2-Bromo-6-ethoxy-4-formylphenyl 4-methoxybenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 379.20 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.
