3-[(2,5-dimethylphenoxy)methyl]-4-methoxybenzaldehyde CAS 438219-83-1

Description

The occurrence of 3-[(2,5-dimethylphenoxy)methyl]-4-methoxybenzaldehyde 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.

3-[(2,5-dimethylphenoxy)methyl]-4-methoxybenzaldehyde (CAS 438219-83-1), molecular formula C17H18O3 and molecular weight 270.32 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, 3-[(2,5-dimethylphenoxy)methyl]-4-methoxybenzaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 270.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
