4-Methoxy-3-{[4-(propan-2-yl)phenoxy]methyl}benzaldehyde CAS 438219-49-9

Description

The occurrence of 4-Methoxy-3-{[4-(propan-2-yl)phenoxy]methyl}benzaldehyde is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Methoxy-3-{[4-(propan-2-yl)phenoxy]methyl}benzaldehyde (CAS 438219-49-9), a certified reference material (molecular formula C18H20O3, MW 284.35 g/mol) for analytical method development and quality control.

4-Methoxy-3-{[4-(propan-2-yl)phenoxy]methyl}benzaldehyde (C18H20O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
