Chemical Structure
Description
The occurrence of 4-Methoxyphenol-2,3,5,6-d4 is closely related to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Methoxyphenol-2,3,5,6-d4 (CAS 159839-23-3) is a high-purity analytical reference standard with the molecular formula C7H4D4O2 and a molecular weight of 128.16 g/mol.
Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Methoxyphenol-2,3,5,6-d4 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.16 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).
