4-Methoxytoluene-2,3,5,6-d4 CAS 350818-57-4

Description

The occurrence of 4-Methoxytoluene-2,3,5,6-d4 is closely related to deuterium isotope labeling, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Methoxytoluene-2,3,5,6-d4 (CAS 350818-57-4), molecular formula C8H6D4O and molecular weight 126.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to deuterium isotope labeling, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Methoxytoluene-2,3,5,6-d4 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.19 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.
