Compared with other compounds in its class, the molecular weight of 292.41 g/mol gives 2-[2,4-bis(2-methylbutan-2-yl)phenoxy]acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-[2,4-bis(2-methylbutan-2-yl)phenoxy]acetic acid (CAS 13402-96-5) is a high-purity analytical reference standard with the molecular formula C18H28O3 and a molecular weight of 292.41 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, 2-[2,4-bis(2-methylbutan-2-yl)phenoxy]acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.41 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
