Chemical Structure

p-Methoxyheptanophenone CAS 69287-13-4 chemical structure

Description

p-Methoxyheptanophenone (CAS 69287-13-4) is a high-purity analytical reference standard with the molecular formula C14H20O2 and a molecular weight of 220.31 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, p-Methoxyheptanophenone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
