Compared with other compounds in its class, the molecular weight of 129.21 g/mol gives 4-Methoxy-d3-toluene-2,3,5,6-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Methoxy-d3-toluene-2,3,5,6-d4 (CAS 1219798-94-3) is a high-purity analytical reference standard with the molecular formula C8H3D7O and a molecular weight of 129.21 g/mol.
Owing to deuterium isotope labeling, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Methoxy-d3-toluene-2,3,5,6-d4 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 129.21 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).
