Chemical Structure
Description
The occurrence of 2-(Benzyloxy)-4-methoxybenzoic acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(Benzyloxy)-4-methoxybenzoic acid (CAS 13618-49-0), molecular formula C15H14O4 and molecular weight 258.27 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H14O4, 2-(Benzyloxy)-4-methoxybenzoic acid contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
