Chemical Structure

4-(4-Methoxyphenyl)phenol CAS 16881-71-3 chemical structure

Description

CATO supplies 4-(4-Methoxyphenyl)phenol (CAS 16881-71-3), a certified reference material (molecular formula C13H12O2, MW 200.23 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H12O2, 4-(4-Methoxyphenyl)phenol contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 200.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
